Paper Published in Remote Sensing
Timothy J. Lang (ST11) is a coauthor on a study called “Evaluating the Detection of Mesoscale Outflow Boundaries Using Scatterometer Winds at Different Spatial Resolutions,” which was recently published in the journal Remote Sensing. This study evaluated the performance of a recently developed technique that uses wind gradients measured by satellite scatterometers to detect outflows from oceanic storms. These outflows, often called cold pools, are important for modifying the marine boundary layer and air-sea interactions, and can help initiate and organize new storms. The technique has been previously validated against buoys and other independent datasets, but this new study led by Georgios Priftis, a student at the University of Alabama in Huntsville (UAH), assessed how scatterometer product spatial resolution (50, 25, and 7 km) impacted results. The 7-km resolution scatterometer data did the best job characterizing the full spatial extent of cold pool boundaries, as well as resolving fine-scale wind features along the boundary. In addition, the study found that using finer-resolution forecast model data, capable of resolving mesoscale storms, as background inputs to scatterometer wind retrieval algorithms helped improve the accuracy of wind retrievals near storm systems. The study provides crucial context for interpreting new global climatologies of oceanic cold pools observed by scatterometers.

USGC Eyes on Earth Podcast - Episode 45: Harmonized Landsat Sentinel (GLS) Data
Interagency Implementation and Advanced Concepts Team (IMPACT) scientist Brian Freitag (ST11) was a guest on the U.S. Geological Survey’s (USGS) podcast “Eyes on Earth” where he discussed the cloud-based processing involved in the merger of the NASA/USGS Landsat and ESA Sentinel-2 satellite data in the HLS project. Some applications of the HLS dataset include looking at inundation events, wildfires, crop harvesting, and to monitor water quality. This publicly available dataset allows researchers to look at these events on a 2-3 day interval and at a high spatial resolution of 30 meters. Agriculture is a major driving force for producing the HLS data and scientists hope that this new dataset will allow for crop forecasting and forest fire analysis on a more frequent time scale than ever before. Cloud computing allows easier analysis of large datasets on the fly, as users don’t need to download terabytes of data onto their own machines. Listen to the podcast recording here.

Regarding staffing, the IMPACT SNWG Project Office recently welcomed a Project Scientist (Andrew Molthan, Ph.D./ST11), a new Budget Analyst (Beth Ewing/RS30), and part-time scheduling assistance (Angel Lopez), while formalizing a contract specialist role (David Hood/Science Projects Branch for Cycle 2) and planning for future support in Systems Engineering, Project Coordination, Procurement, and Science Data Analysis.
New SERVIR Journal Publication Shows Paths Forward for Flood Early Action
Disconnects between forecasters and decision-makers worldwide can often result in greater flood impacts. To stem those impacts, the humanitarian and Earth science communities have begun to come together to develop programs for anticipatory action or forecast-based early action (FbA). Still, Earth observation (EO) scientists have not been able to transition the full breadth and capability of EO and related forecasts to flood managers, especially before disasters strike. In a new paper, experts from the SERVIR’s Science Coordination Office, the University of Alabama in Huntsville (UAH), NASA Headquarters, Columbia University IRI, and the Red Cross Red Crescent Climate Centre provide suggestions to help ensure satellite data and forecasts are used to their full potential. The paper consolidates the forecast lead times required for some 45 flood early actions and presents calls to action to connect EO to different FbA phases, particularly in the design and evaluation phases. The article, led by UAH graduate student Claire Nauman with advising from Eric Anderson and Amanda Markert, and published in the Journal of Applied Remote Sensing, shines light on opportunities for the Earth observations community to better support FbA efforts for flood management. https://doi.org/10.1117/1.JRS.15.032002
Special Issue with 40-Papers Published on "Greenhouse Gases, Short-Lived Climate Pollutants and Aerosol Pollution in South/Southeast Asia - Drivers, States, and Impacts"
Krishna Vadrevu (ST11) led a special issue in collaboration with Toshimasa Ohara (NIES, Japan) in the Environmental Pollution journal that has an impact factor of 6.8. Due to the rapid economic growth and high population pressure, the air quality in South/Southeast Asian countries has worsened with an increase in Greenhouse gases (GHGs), Short-Lived Climate Pollutants (SLCP), and aerosol emissions. Important sources of these emissions in the region include coal burning, exhaust from vehicle engines, industrial sources and biomass burning. The special issue focused on the pollution problem based on the Drivers/Pressures, States, Impacts and Response (DPSIR) framework, which attracted wide attention in the region. More than 90-manuscripts were submitted to the special issue, of which 40-papers were finally published with fifteen papers on measurements and modeling, ten on drivers, nine on impacts and six articles on mitigation and control. The authors are mainly from regional countries. The special issue is one of the outputs from meetings and workshops organized in Asia as part of the NASA Land Cover/Land Use Change Program funded South/Southeast Asia Research Initiative (SARI) that Vadrevu is leading.

Paper Assessing the Impact of COVID-19 Lockdown on Air Quality Over India Published in Sustainable Cities and Society Journal
Pawan Gupta (ST11/USRA) and Falguni Patadia (ST11/USRA) co-authored a paper titled “Surface and satellite observations of air pollution in India during COVID-19 lockdown: Implication to air quality”, that was recently published in Sustainable Cities and Society Journal. The study uses multiple satellite and ground data to analyze criteria air pollutants over both individual Indian cities and the entire Indian sub-continent region.
A nationwide lockdown was imposed in India during March-May 2020 to prevent the spread of COVID-19. This interrupted several anthropogenic emission sources and reduced mobility nationwide and created a temporary air quality improvement. The study found a significant reduction in surface measurements of nitrogen dioxide (NO2) (46–61 %) and fine particulate matter (PM2.5) (42–60 %) during the lockdown period that are also corroborated by the reduction in satellite observed aerosol optical depth (AOD) (3–56 %) and tropospheric NO2 column density (25–50 %) data over multiple cities. Other species, namely coarse particulate matter (PM10) (24–62 %), ozone (22–56 %) also showed a substantial reduction. This temporary air quality improvement underpinned the importance of reducing emissions from other sectors along with transportation and industry. The observed improvement in Air Quality Index (25-56%) provides a benchmark for air quality improvements achievable through air quality management and policy changes.
SPoRT Graduate Student Holley Kenward Receives Best Student Poster Award
SPoRT graduate student Holley Kenward (ST11) received the Best Student Poster Presentation award at the Fourth Symposium on Tropical Meteorology and Tropical Cyclones at the 101st American Meteorological Society Annual Meeting. Kenward, who is a UAH graduate student advised by SPoRT research associate Erika Duran, presented her research on the tropical cyclone diurnal cycle. Her results indicate that hurricanes tend to be smaller overnight than they are during the day and that the air nearest the ocean surface is moister during the day than at night. These results have potentially important implications for hurricane intensity and rainfall forecasting. Ms. Kenward is now conducting trajectory analyses in simulated hurricanes to determine how the diurnal cycle affects a hurricane’s interaction with its environment.

Nature Scientific Reports on COVID Related Pollution in India
Krishna Vadrevu (Earth Science Branch) published a paper in Nature Scientific Reports on COVID related pollution in India. https://www.nature.com/articles/s41598-020-72271-5. In early 2020, the COVID-19 virus started to spread rapidly across the globe into most countries, including India, where the first case was reported on 1/30/20. Since then, COVID has resulted in the deaths of ~148439 people to date. To curb the spread of COVID, earlier stringent lockdown measures were in effect. With the COVID-19 pandemic and a lockdown situation in India, a reduction in air pollution was expected as the main source of pollutants is largely human activities. However, the specific amount of pollution decrease in India is not well-documented, hence this study’s focus. Since cities are hotspots of air pollution, we focused on 41 cities based on their population size.
We analyzed how air pollution varied during the lockdown period compared to the previous year and the pre-lockdown period. We specifically used TROPOMI NO2 data and MODIS Aerosol Optical Depth (AOD) over 41 cities to characterize the pollution. Our results suggested a 13% NO2 reduction during the lockdown (3/25–5/3/20) compared to the pre‑lockdown (1/1–3/24/20) period. Also, a 19% reduction in NO2 was observed during the 2020‑lockdown compared to the same period during 2019. The study highlights the top cities where NO2 including some drivers including some robust time series analysis. Results also highlight spatial differences in NO2 pollution due to city characteristics based on location and population. The results highlight the impact of the human footprint on India’s air pollution levels during COVID-19 captured by the remote sensing datasets.

SPoRT Research Results Reported in Inside Science: "Satellite Imagery Boosts Scientists' Understanding of Thundersnow"
Emily Berndt (ST11) and Sebastian Harkema (UAH/SPoRT) were recently interviewed by Inside Science’s Catherine Meyers about his Ph.D. research of lightning in snowfall and results that were presented at the American Meteorological Society Annual Meeting. As a graduate student supported by the Short-term Prediction Research and Transition (SPoRT) Center and NASA’s FINNEST program Harkema has examined winter storms that produce lightning with the NASA/NOAA GOES-16 Geostationary Lightning Mapper and Advanced Baseline Imager. The article highlights his masters’ work that lightning characteristics in winter storms (thundersnow) tend to be larger and longer-lasting compared to lightning in thunderstorms and thundersnow is well correlated with storms that produce a lot of snowfall but is spatially separated from the heaviest snowfall rates.
In addition, the article highlights recent research results in which the NASA/NOAA GOES-16 satellite imagery suggests that ice particles develop at the cloud top and become smaller prior to the development of thundersnow. Prior to thundersnow initiation, and when examining multispectral imagery, it was found that there were patterns in the coloration in the imagery which are used to infer cloud characteristics such as cloud-top temperature, phase, and size. Few studies have examined the trends in satellite imagery leading up to lightning in winter storms even though winter storms often cause tremendous disruption to societal and economic activities. These results suggest that satellite imagery can be associated with the physical process that lead to thundersnow. The article includes comments from other prominent researchers such as Patrick Market, a thundersnow researcher at the University of Missouri in Columbia, who noted “There’s a pure science aspect of this work, about understanding the microphysics inside a cloud, but there is also the applied aspect of improving the forecast. It’s ringing all the bells.” Harkema’s work aligns with the SPoRT mission to transition NASA research and capabilities to stakeholders. These new insights will help transform conceptual models and provide insight into ways to analyze next generation NASA/NOAA observations to improve forecast skill, translating science to operational decisions and societal benefit.

Key Technology Proposal Selected to Advance Lightning Mission Concept
Lightning research and instrument development are a core area for Marshall Space Flight Center (MSFC) that has culminated in several successful satellite missions to observe thunderstorms. An innovative new mission concept—CubeSpark—being formulated by MSFC and Los Alamos National Laboratory (LANL) will utilize a constellation of CubeSats to study lightning and thunderstorms on a global scale like never before. MSFC scientists, Patrick Gatlin (ST11) in collaboration with Timothy Lang (ST11), were involved in a proposal led by scientists at LANL that was recently selected by NASA’s Earth Science Technology Office to advance the CubeSpark concept by miniaturizing a key payload. This technology development will complement a project recently funded through MSFC’s Center Innovation Fund to design a new lightning imager for CubeSpark.
NASA Earth Science Data Systems 2020 Highlights Features the IMPACT Team
NASA’s Earth Science Data System (ESDS) Program recognizes that new strategies are required in order to meet the data needs of the research community in this modern age. ESDS also strives to encourage the use of Earth observation data by a broader user community. The Interagency Implementation and Advanced Concepts Team (IMPACT) program addresses these data needs through its focus on improving data acquisition, management, analysis, and exchange. IMPACT supports the ESDS Program mission with multiple projects in three focus areas. Some of the projects are:
Satellite Needs Working Group (SNWG) is comprised of a team which serves as the data liaison between the U.S. Group on Earth Observations SNWG and ESDIS. Using the biennial surveys of participating agencies conducted by SNWG to assess their needs for U.S. government Earth observing satellite applications, the team creates a profile of agency needs and develops mappings to data that meet those needs.
Data Curation for Discovery (DCD) designs and implements a systematic plan to assist other agencies in incorporating NASA Earth observation data into their workflows. The DCD team improves the discoverability of NASA Earth science data and other curated Earth observation data in trusted catalogs and platforms.
Analysis and Review of CMR (ARC) focuses on improving the discoverability, accessibility and usability of NASA’s Earth science data holdings by ensuring all NASA collection and granule level metadata records in NASA’s Common Metadata Repository (CMR) meet a minimum standard of quality. The ARC team reviews the metadata for these collections, identifies opportunities for improvement in the records, works with the data providers, develops methods to automate the quality evaluation checks, and develops processes to minimize issues in the future.
Airborne Data Management Group (ADMG) develops systematic approaches to airborne data management and stewardship. The ADMG develops best practices for airborne data management and provides a knowledge base for airborne campaigns, data centers, managers, scientists and users.
The Algorithm Publication Tool (APT) enables open, reproducible science by helping scientists write standardized, high-quality Algorithm Theoretical Basis Documents (ATBDs) collaboratively via a single end-to-end authoring tool. The APT establishes and implements a standardized ATBD governance process and provides a free and open portal to ensure all ATBDs are discoverable and accessible to users.
Public-Private Open Data Partnership (OpenData). The goal of this effort is to:
- demonstrate the potential of cloud computing in applying algorithms to the data to enable processing and analytics at scale;
- improve over the existing methods of data search and minimize reliance on internal search tools; and
- explore partnerships in the field of artificial intelligence and machine learning in order to utilize these techniques in novel applications to address existing data discovery, access and use challenges.
Paper on Geophysical Retrievals from the Advanced Microwave Precipitation Radiometer Published
Timothy J. Lang (ST11) is a co-author on a paper, titled “Dual-Polarization Deconvolution and Geophysical Retrievals from the Advanced Microwave Precipitation Radiometer during OLYMPEX/RADEX,” that was recently accepted in the Journal of Atmospheric and Oceanic Technology. The study focuses on using the Advanced Microwave Precipitation Radiometer (AMPR) instrument to retrieve high-resolution swaths of cloud liquid water path, atmospheric water vapor, and ocean surface wind speed during the Olympic Mountains Experiment/Radar Definition Experiment (OLYMPEX/RADEX) that occurred in northwest Washington state in late 2015. The research, led by AMPR team members Corey Amiot of the University of Alabama in Huntsville and Sayak Biswas of The Aerospace Corporation, demonstrated the ability of AMPR’s dual-polarimetric measurements to make accurate retrievals of these important atmospheric parameters. Lessons learned from this research are also being used in AMPR science analyses from the Cloud, Aerosol, and Monsoon Processes Philippines Experiment (CAMP2Ex, 2019) and the Investigation of Microphysics and Precipitation for Atlantic Coast-Threatening Snowstorms (IMPACTS, 2020) campaigns. This paper thus marks the culmination of AMPR’s dual-polarimetric technology upgrade that occurred prior to 2011, and paves the way for geophysical retrievals to become a routine science product provided by the AMPR airborne instrument.
Data Science Challenge Accepted for Institute of Electrical and Electronics Engineers (IEEE) Emeerging Techniques in Computational Intelligence (ICETCI) 2021
A data science challenge proposal submitted by Interagency Implementation and Advanced Concepts Team’s (IMPACT) Manil Maskey (ST11) was accepted by the IEEE ICETCI 2021. The challenge seeks artificial intelligence (AI) techniques to detect flood extents from Synthetic Aperture Radar (SAR) images. Iksha Gurung of the IMPACT team led the generation of training data for the challenge in close collaboration with the MSFC Disasters Team and the University of Alabama Earth System Science Center. Over the summer, students across USA and Europe worked together with domain experts to create and curate the flood extents on SAR dataset. The IMPACT team anticipates several submissions to this challenge allowing novel ways to detect flood extents that could be used for real time decision making.
SERVIR Land Cover Monitoring Activities Highlighted During Recent Global Forest Observation Initiative (GFOI) Webinar
SERVIR’s activities in land cover monitoring were recently highlighted at a webinar organized by the Global Forest Observation Initiative (GFOI), on 12/15/20. The webinar covered the high spatial resolution Planet and AirBus imagery licenses being provided by the Government of Norway for forest monitoring (see: https://www.planet.com/nicfi/). On behalf of SERVIR, the Science Coordination Office (SCO)’s Emil Cherrington gave a short presentation highlighting how the SERVIR-West Africa consortium has already started exploring the use of the Planet imagery in services related to monitoring of deforestation and forest degradation from charcoal production and from artisanal gold mining in Ghana. Cherrington also highlighted the recent SERVIR-West Africa capacity building webinar on the new data offerings, which was held in late November.
TROPICS Applications Quarterly Meeting
Emily Berndt (ST11) the Deputy Program Applications lead for the Time-Resolved Observations of Precipitation structure and storm Intensity with a Constellation of Smallsats (TROPICS) Mission and Erika Duran (UAH) hosted a quarterly TROPICS Applications meeting on 12/11/20 to foster interaction between the community of end users and the science team. The full mission, composed of six smallsats, is planned to launch in early 2022 but the science team gained approved to launch the single qualification unit in June 2021 as a “pathfinder” mission. During the meeting the PI, Bill Blackwell (MIT LL), gave a mission status update. This update was integral to the community of end users who recommended the “pathfinder” mission during the February 2020 Applications Workshop as an important step to preparing to use the mission in applied research and operations. In addition, Juan Crespo (JPL) gave a presentation on NASA’s Cyclone Global Navigation Satellite System (CYGNSS) mission and potential synergies with TROPICS. Both missions have a strong emphasis on tropical cyclone research and applications and their operations will overlap. The collaboration between SPoRT and Applied Sciences to host TROPICS Applications quarterly meetings connects stakeholders to the science team to inform users and ready them [before launch] to use the data, thus enabling rapid ingest of observations quickly after launch.
Proposal Submitted to NOAA Selected for Funding
Kevin Fuell (UAH at SPoRT) was awarded a proposal submitted to the National Oceanic and Atmospheric Administration (NOAA) Joint Polar Satellite System (JPSS) Proving Ground and Risk Reduction (PGRR) Program titled “Micro-lesson Training Series for JPSS Snow, Ice, and Soil Moisture Products.” The proposal is inclusive of members of the MSFC SPoRT team, Emily Berndt (NASA/SPoRT), Anita LeRoy (UAH), and Frank LaFontaine (Jacobs). The goals of this proposal are to increase the awareness within both the operational and research communities of the existing NASA/NOAA JPSS snow and ice products derived from infrared and microwave sensors (VIIRS, ATMS, AMSR2), as well as soil moisture (AMSR2) and to increase utilization of these products in data sparse regions for daily operational analysis and research modeling efforts. Products such as snow cover and SWE have a legacy from instruments like NASA/MODIS and AMSR-E and the JPSS capabilities are a next-generation version of these early accomplishments. This proposal work includes the development of a training series using the ‘micro-lesson’ format with tailored sections for operations and research audiences. User and researcher on-the-job support are planned to occur in the form of ‘Quick Guides’ which allow an easy reference of the product’s strengths, weaknesses, and interpretations, as were covered in detail by the micro-lessons. Both of these training formats were developed by NASA/SPoRT and used extensively within training activities for user preparations for JPSS and GOES-R series satellites and their use has been adopted by several international satellite agencies such as Europe’s EUMeTrain and Japan’s JMA. The development of this training series will allow the team to engage, train, and assess various user groups in order to fill gaps in current product understanding and to discover possible derivatives where JPSS product developers may further enhance operational and research utility. The proposal team will engage NASA and NOAA research groups conducting land surface modeling work to understand how their needs different from the operational community and how they can also be served by this training series. The inclusion of JPSS snow, sea ice, and soil moisture products in modeling efforts is particularly important to NASA researchers developing the Land Information System (LIS) as well as to the NOAA National Water Center (NWC) in the development of strategies for the National Water Model (NWM).
SERVIR Applied Sciences Team Hydrologic Model Informs Ugana Water Management Decisions
Over the past several years, SERVIR has built the capacity of partners in East Africa to use satellite data in a hydrologic model, the Ensemble Framework for Flash Flood Forecasting (EF5), as part of the 2015 SERVIR Applied Sciences Team project led by Yang Hong (University of Oklahoma, Norman). The EF5 model is now being actively used in Uganda to plan water supply intakes in towns that have no stream gauges. In December, Uganda’s Ministry of Water and Environment reported using SERVIR-E&SA’s model for regional streamflow monitoring and forecasting to perform hydrological assessments in the country’s Kyoga Basin. These rivers lack on-site gauging stations, making Earth observations critical for designing water supply systems and other water management engineering projects.

The Short-term Prediction Research and Transition (SPoRT) Center recently published their 2020 Year in Review Blog Post (https://weather.msfc.nasa.gov/sport/blog/articles/2021/01/20210105-SPoRT-Year-In-Review-2020/) This blog post provides a high level overview of the accomplishments and successes achieved by the entire SPoRT Team, civil servants, contractors and graduate students. This blog post is also a testament to the hard work and dedication of the team, despite working away from one another for nearly the entire year.
Proposal Selected for Funding
Emily Berndt (ST11) was awarded a proposal submitted to the National Oceanic and Atmospheric Administration (NOAA) Joint Polar Satellite System (JPSS) Proving Ground and Risk Reduction (PGRR) Program titled “Spatially and Temporally Enhanced NUCAPS Sounding Products for Emerging Applications.” The proposal is inclusive of members of the MSFC Short-term Prediction Research and Transition (SPoRT) team Erika Duran (UAH), Kevin Fuell (UAH), Jon Case (ENSCO), Kris White (NOAA NWS), and Frank LaFontaine (Jacobs) and continues a collaboration with JPL scientists. This work continues previously applied-research projects to develop innovative capabilities and products from NASA/NOAA satellite sounding observations to support operational short-term forecasting challenges related to storm and hurricane intensity, severe weather, and fire weather. Over the three year project the team will utilize trajectory modeling and satellite soundings from multiple NASA/NOAA platforms to increase the spatial coverage and time dimension of these observations by advancing them forward in time. The team will validate the resulting products, conduct applied research related to severe weather and hurricanes, and experimentally transition the capabilities to SPoRT stakeholders for use in operations. The project will advance the state of the science through innovative capabilities and analysis and maximize the societal benefit of joint NASA/NOAA investments through engaging with stakeholders.
IMPACT Selected for Expanded Satellite Needs Working Group (SNWG) Role
The IMPACT project has been selected by the Earth Science Data System program at NASA Headquarters for a significantly expanded role for the SNWG. Current role is being expanded to manage the implementation of new data products and expand data system capabilities to meet the needs of SNWG requests. IMPACT will be responsible for managing an additional effort of over $20 million.
NASA SPoRT Wildfire Work Used by Jack Kaye for Briefing on Capitol Hill
On 12/14/20, Short-term Prediction Research and Transition (SPoRT) Team members were notified that work they had published and contributed to the science results portal was going to be incorporated into a Capitol Hill briefing on NASA research related to wildfire. Of particular interest was the Evaporative Stress Index work led by Christopher Hain (ST11), which uses satellite remote sensing to identify when vegetation is stressed due to water conservation efforts by the vegetation because of a lack of water. An additional focus was the lightning-initiated wildfire identification efforts to improve fire identification and response. This work is led by Christopher Schultz (ST11), and has gone though and classified lightning frequency, polarity, rainfall rates, and total rainfall at the time of wildfire ignition to determine the distribution of wildfire holdover events (where smoldering occurs for several days before fire breaks out) which can surprise wildfire fighting operations. All three content pieces were picked up in NASA’s Science Results Portal:
SERVIR Science Coordination Office (SCO) Hosts Flood Mapping Virtual Training to Support Critical Needs in South and Southeast Asia
Floods in Cambodia killed 42 people and affected over 175,000 families in October 2020. This challenge brought UN World Food Programme (WFP) Cambodia together with SERVIR to codevelop the new Hydrologic Remote Sensing Analysis for Floods (HYDRAFloods) service that improves the frequency and resolution of flood map updates. To empower WFP and SERVIR hubs to use this service, SERVIR hosted a HYDRAFloods virtual training, 11/3-12/3/20. The virtual training detailed various techniques of surface water mapping and the step-by-step methodologies for accessing, preprocessing, and producing data fusion surface water maps. Kurt Burja, Programme Policy Officer for WFP Cambodia, said “HYDRAFloods made it possible to… produce estimates of the population affected by the floods to guide the immediate response...and inform the formulation of a more comprehensive response plan.”
American Meteorological Society (AMS) Journal of Applied Meteorology and Climatology Article "Testing Passive Microwave Hail Retrievals Using GPM DPR Ku-Band Radar" Accepted
Sarah Bang (ST11) and Daniel Cecil (ST11) authored a paper titled “Testing Passive Microwave-Based Hail Retrievals using GPM DPR Ku-band Radar” that was recently accepted to the Journal of Applied Meteorology and Climatology (JAMC). In a previous paper, Bang and Cecil created a passive-microwave hail retrieval algorithm that is trained on surface hail reports to estimate the probability of severe hail. The retrieval is used to construct a nearly global climatology of severe hail using Global Precipitation Measurement (GPM) passive-microwave data. In this paper, Bang and Cecil assess the performance of their passive-microwave severe hail retrieval, as well as several other retrievals from the literature, using GPM dual-frequency precipitation radar (DPR) data.
The retrievals are assessed based on how tightly they constrain the radar reflectivity at -20C (where hail would be expected in the cloud), and how this measured radar reflectivity aloft varies geographically. The paper also outlines a methodology for screening out surface ice and snow artifacts and adjusting passive-microwave brightness temperatures from different microwave radiometer footprints to make possible the application of the hail retrieval to multiple satellite platforms.

Risk Financing Technical Assessment Group (TAG) Present Findings and Recommendations to SERVIR Network
Risk financing programs can protect millions of households, communities, farmers, and pastoralists, from shocks such as floods and droughts. Satellite data are becoming more prevalent in such programs, but not without challenges. To better understand the risk financing landscape and role of Earth observations, SERVIR collaborated with the NASA Earth Sciences Program Risk Reduction & Resilience Program Advisor to convene a technical assessment group (TAG). The TAG conducted research and held conversations with SERVIR hubs and other experts in the field, to prepare a scoping report on gaps and recommendations for SERVIR and the applied Earth observations community. The TAG presented its findings including five short term and six long term recommendations to the SERVIR network on 11/20/20. Included among the recommendations were 1) encouraging the adoption of index insurance quality certification initiatives, 2) contributing to EO-based loss databases, and 3) expanding stakeholder groups to include economic and financial partners.
Paper Comparing Ocean Winds Near Thunderstorms and Non-Thunderstorms Published in Remote Sensing Journal
Timothy J. Lang (ST11) is the sole author on a paper, titled “Comparing Winds Near Tropical Oceanic Precipitation Systems with and without Lightning,” that was recently accepted and published in the journal Remote Sensing. The study takes a novel approach to comparing ocean winds near thunderstorms and precipitation systems that don’t produce lightning, by combining ocean wind, lightning, and precipitation information from multiple NASA datasets – including the Cyclone Global Navigation Satellite System (CYGNSS), the International Space Station Lightning Imaging Sensor (ISS LIS), and the Integrated Multi-satellitE Retrievals for Global Precipitation Measurement (IMERG). Data from the Advanced Scatterometer (ASCAT), the Geostationary Lightning Mapper (GLM), and the World-Wide Lightning Location Network (WWLLN) were also used in the study. Though the main hypothesis being tested was that thunderstorms have consistently stronger surface winds compared to non-thunderstorms, the results of the global analysis over the tropical oceans were more mixed. ASCAT wind measurements, which tend to be more affected by the presence of precipitation, supported the hypothesis, but CYGNSS wind measurements (which are less affected by precipitation) did not. However, both ocean wind datasets agreed that the presence of precipitation systems (with or without lightning) are associated with significantly increased wind speeds over the background flow. In addition, thunderstorms are consistently associated with heavier rainfall over the global oceans compared to non-thunderstorms. The results demonstrate that accurate space-based ocean wind measurements near precipitation continue to be a major challenge for the scientific community. This work also has implications for understanding how wind outflows from precipitation systems impact the global climate, as well as the relative importance of thunderstorms for affecting the planetary boundary layer.

New AGU Earth and Space Science Article Developing a Technique to Use Space Station Video for Scientific Analysis
A recently accepted article in American Geophysical Union’s (AGU) Earth and Space Science highlights a Python-based technique to identify lightning and its spatial characteristics within nadir pointing video frames from the International Space Station. The video-derived lightning characteristics were compared against the ISS Lightning Imaging Sensor (LIS), Geostationary Lightning Mapper (GLM), and ground based lightning information. Results indicate that the video-derived lightning identification was within 266 km2 of GLM flash footprints, indicating good spatial correspondence between the two datasets. Reverse geolocation of individual frames using lightning data alone proved difficult; however, using city light features from Visible Infrared Imaging Radiometer Suite (VIIRS) Day-Night-Band reduced the uncertainty in pointing angle and reverse geolocation. Open source Python-based software was developed to help future investigators reverse geolocate nadir images from the ISS from systems like METEOR (https://github.com/nasa/ISS_Camera_Geolocate). The article is located at: https://agupubs.onlinelibrary.wiley.com/doi/10.1029/2020EA001085.

Publication on Use of Synthetic Aperture Radar for Flood Detection
MSFC Earth Science Disasters Team and SPoRT team members are coauthors on a recent publication “Flood Hazard and Risk Assessment of Extreme Weather Events Using Synthetic Aperture Radar and Auxiliary Data: A Case Study”, led by Esayas Gebremichael of Texas Christian University. In the manuscript by Gebremichael, Earth Science Branch’s Andrew Molthan, Jordan Bell, Lori Schultz, and Christopher Hain, synthetic aperture radar (SAR) backscatter and coherence information is used to assess the extent of flooding following significant rainfall events in the region of Houston, Texas, which often experiences widespread riverine and flash flooding as the result of severe weather and tropical cyclones. Capabilities of SAR for water mapping were explored by looking for dark radar regions indicating standing water but also the use of coherence products, or the similarity in the phase and backscatter information comprised from multiple scenes. Information from the UAVSAR airborne instrument and other data sets were used for calibration of the output results. Gebremichael initiated the work supporting the manuscript while working with the MSFC team and continues to collaborate with MSFC personnel after pursuing a tenure-track position at Texas Christian University. Team members plan to continue collaborating with Gebremichael while broadening their SAR expertise. The full article is available online: https://www.mdpi.com/2072-4292/12/21/3588

Collaboration with University of Alabama on New Technique for Estimating Floodwater Depth
Ronan Lucey (ST13/UAH) of the MSFC Earth Science Disasters Team is a co-author an accepted paper entitled “Google Earth Engine (GEE) Implementation of the Floodwater Depth Estimation Tool (FwDET-GEE) for Rapid and Large Scale Flood Analysis,” published in IEEE Geoscience and Remote Sensing Letters. The paper introduces a new implementation of the Floodwater Depth Estimation Tool (FwDET) in GEE that that is open access, utilizes cloud-stored surface elevation data, and performs geospatial analytics on the fly to translate satellite-based estimations of flood extent into information on flood depth, extending the value and utility of satellite remote sensing information. Within the Earth Science Disasters Team, collaborations between Lucey, University of Alabama, and others will advance the team’s capacity to produce timely floodwater data during flood activations that require emergency response and post-flood assessment. The tool has the potential to be utilized by the NASA Disasters Program as a research tool and in flood response activations to provide timely floodwater depth information to key stakeholders. These activities also further build and advance collaborations with the University of Alabama’s Surface Dynamics Modeling Lab (Sagy Cohen, PI), potentially the National Water Center, and benefits other internal collaborations such as shared technical capabilities with the SERVIR Science Coordination Office.

IMPACT Publicly Releases Sub-Orbital Catalog Portal on Earthdata Search Website
Christopher Lynnes (Goddard Space Flight Center), a team member of both MSFC Interagency Implementation and Advanced Concepts Team (IMPACT) and NASA’s Earth Science Data and Information System (ESDIS), worked with the Airborne Data Management Group (ADMG) recently to improve airborne and field data discovery in Earthdata Search. The ADMG team members identified needed metadata tags and humanizers using comparisons of existing metadata elements in the Common Metadata Repository (CMR) with the ADMG inventory information. Lynnes subsequently constructed the Sub-orbital Catalog Portal, a focused interface that provides a similar environment to Earthdata Search, but reduces the overhead for targeted users such as those locating airborne and field investigation data. The outcome for users is a significant improvement in more meaningful search results when using search filters. The Sub-orbital Catalog Portal is now publicly available at https://search.earthdata.nasa.gov/portal/suborbital/search.
Paper Published in Remote Sensing Journal
Emily Berndt (ST11)published a peer-review manuscript titled “Gridded Satellite Sounding Retrievals in Operational Weather Forecasting: Product Description and Emerging Applications” in Remote Sensing within the special issue on Satellite Data Application, Validation and Calibration for Atmospheric Observation. Over the last several years, Berndt has led a funded project to develop gridded satellite sounding retrievals for the operational forecasting community. The project has been executed as a collaborative effort between the Short-term Prediction Research and Transition (SPoRT) Center and the NOAA Joint Polar Satellite System Proving Ground and Risk Reduction Program. Additional SPoRT team members contributed to analysis (Dr. Erika Duran / UAH), data visualization and data production (Roger Allen / Jacobs and Frank LaFontaine / Jacobs), and end user outreach (Kris White / NWS Huntsville). The paper presents a standardized methodology for gridding satellite sounding retrievals and development of derived products to support short-term weather forecasting. Several analysis examples are presented in the paper such as application in pre-convective weather forecasting, monitoring the potential for fire weather, tracking the Saharan Air Layer, and the influence of stratospheric air intrusions on weather systems. This paper represents development of approaches to better synthesize remote sensing observations and novel concepts to support application of these observations beyond the original intent of the data, ultimately increasing the availability and usability of joint NASA and NOAA investments. As a successful transition of research to operations/operations to research, the capability described in this paper has been transitioned the entire NOAA National Weather Service for use in real-time weather forecasting operations.

Paper on Open Source Software to Retrieve Three-Dimensional Winds in Convection Accepted in Journal of Open Research Software
Timothy J. Lang (ST11) is a co-author on a paper, titled “PyDDA: A Pythonic Direct Data Assimilation framework for wind retrievals,” that was recently accepted for publication in the Journal of Open Research Software. The paper was led by Argonne National Laboratory (ANL), and reports on a new open source software package that performs retrievals of three-dimensional (3D) winds in convection using ground-based Doppler radar data. The software derives from a prototype Python module called MultiDop. MultiDop development was led by Lang with seed funding from the NASA Weather program during Fiscal Year 2016. ANL then refined and enhanced the approach to be faster, more robust, and more user-friendly, leading to the new PyDDA package. The 3D wind retrieval capability provided by PyDDA, when used in concert with networks of Doppler radars throughout the globe (including the U.S. NEXRAD network), will help expand the Program of Record (PoR) for the forthcoming NASA Aerosol, Cloud, Convection, and Precipitation (ACCP) mission.
PyDDA is also expanding the data provided by the Global Precipitation Measurement (GPM) Validation Network (VN). PyDDA software may be obtained here: https://github.com/openradar/PyDDA.

Validating Raindrops Measured from Space for the Global Precipitation Measurement Mission
For the past decade, Marshall Space Flight Center (MSFC) has been tasked with validation of the Global Precipitation Measurement (GPM) core satellite—NASA’s flagship Earth-observing satellite mission that measures the size of raindrops to observe where and how much precipitation occurs on a global scale. To do this, MSFC has obtained measurements of individual raindrops from around the globe and translated them using networks of operational ground-based weather radars for comparison with the GPM satellite estimates. This Validation Network and its application to assess GPM satellite retrievals of raindrop size are the topics of a recent study led by Dr. Patrick Gatlin (Earth Science Branch), with contributions from Dr. Walt Petersen (Science Research and Projects Division) and scientists at Goddard Space Flight Center, that was recently published in the journal Atmosphere. The results of this study are important because they provide a fundamental assessment of GPM satellite algorithms that is used by the GPM mission to improve the accuracy of its global maps of precipitation.

SERVIR Applied Sciences Team Project Makes Impact in Recent Nepal Floods
Each year torrential rains spell disaster for communities in mountainous regions of Nepal. To help mitigate this impact, a decision-making tool was developed by Dr. Patrick Gatlin and others on SERVIR’s Applied Sciences Team, led by Dr. Ashutosh Limaye, and at its hub in Nepal. The High Impact Weather Assessment Toolkit (HIWAT) provides high-resolution forecasts of precipitation that are used for predicting the rise and fall of water levels in the numerous rivers that cut through the Himalayan Mountains.
Recently, these HIWAT derived streamflow predictions were used at the local level in a city outside Kathmandu, Nepal to inform decision-makers of a potential disastrous flood event that was to occur. As a result of this new information and training on how to use it, district leaders were able to take preventative measures by digging a deeper river channel in advance of the flood event. These actions kept the city’s cement factory, which is one of its biggest industries, from receiving any damage—something that has not been the case in years past before they had such a tool as HIWAT. This is yet another example of how SERVIR connects space to village and continues to develop innovative solutions that address critical challenges in developing countries.

New SPoRT Satellite Product Adopted for Preliminary Assessment by the National Hurricane Center
The National Hurricane Center (NHC) has adopted a new satellite product developed by the Short-term Prediction Research and Transition (SPoRT) Center for preliminary testing. This product is derived from National Oceanic and Atmospheric Administration (NOAA) Unique Combined Atmospheric Processing System (NUCAPS) satellite sounding retrievals, which use the heritage NASA AIRS Science Team version 5.9 algorithm. NUCAPS retrieves vertical profiles of temperature, humidity, trace gases, and cloud properties through a combination of both infrared and microwave instrumentation from a number of platforms, including the Suomi-National Polar-orbiting Partnership (S-NPP), a joint NASA-NOAA satellite. The product includes both temperature and moisture anomalies, which are important for tropical cyclone (TC) intensity prediction, displayed in a storm-relative framework that makes it easier for forecasters to interpret. A web page that displays these anomalies in real time for the 2020 Atlantic hurricane season was created in collaboration with Rebekah Esmaili at the Science and Technology Corporation (STC)/Joint Polar Satellite System (JPSS).
Images demonstrate regions of moist/dry air, as well as gradients in temperature and moisture, capturing important features such as dry air intrusions that can inhibit TC intensification. This product allows forecasters to diagnose short-term changes in TC thermodynamic structure, and supplements Geostationary Operational Environmental Satellite (GOES) water vapor imagery by providing the amount and location of moisture at a number of different vertical levels in the atmosphere. SPoRT will solicit feedback from forecasters at NHC over the coming months to further enhance the product in preparation for the 2021 Atlantic Hurricane Season.

Paper on the International Space Stations Lightning Imaging Sensor Accepted in Journal of Geophysical Research
Rich Blakeslee (ST11/Emeritus) and Timothy J. Lang (ST11) are lead authors on a paper, titled “Three years of the Lightning Imaging Sensor onboard the International Space Station: Expanded Global Coverage and Enhanced Applications," that was recently accepted for publication in Journal of Geophysical Research: Atmospheres. Several other Earth Science Branch-affiliated scientists also contributed to the study. The paper provides an overview of the International Space Station Lightning Imaging Sensor (ISS LIS), which has provided global observations of lightning from the ISS since March 2017. ISS LIS is the only existing instrument providing global observations of total lightning - day and night, with high uniform detection efficiency over land and ocean.
The mission builds on the highly successful Optical Transient Detector (OTD; 1995-2000) and Tropical Rainfall Measuring Mission (TRMM) LIS (1997-2015) instruments, and extends global lightning monitoring to higher latitudes (+/- 55°) than were previously available from TRMM LIS. Due to the uniqueness and importance of ISS LIS measurements, the journal editor has also recommended a highlight of the paper to appear in the American Geophysical Union's Eos magazine. ISS LIS is nearing the end of the NASA Senior Review process, where Lang led a recent presentation on ISS LIS science to a panel convened by NASA Headquarters, and an extension of the mission to as late as Fiscal Year (FY) 2024 has been requested. A Senior Review decision is expected by the end of FY 2020.
SPoRT Scientists Lead hurricane Forecast Briefings for NOAA's Hurricane Research Division
Each year, the Hurricane Research Division (HRD) of the National Oceanic and Atmospheric Administration (NOAA) conducts a field campaign to provide real-time observations to forecasters at the National Hurricane Center. The field program's three aircraft collect data that are invaluable in improving the accuracy of hurricane forecasts. An integral part of this field campaign is a daily weather briefing led by scientists from HRD, other federal agencies, and universities. This briefing is used to make important decisions regarding aircraft deployment and flight patterns. Erika Duran and Patrick Duran of the Short-Term Prediction Research and Transition (SPoRT) project led HRD’s daily weather briefings for the week of 8/3-7/20. The briefings consisted of real-time analysis of satellite and aircraft datasets along with an interpretation of model forecasts. The daily meetings provided a forum to feature existing and newly developed SPoRT products to 50-90 hurricane researchers and forecasters from across the nation. For example, the Gridded NOAA Unique Combined Atmospheric Processing System (NUCAPS) sounding product, which SPoRT is collaborating with other agencies to develop, proved highly useful in characterizing dry air near Hurricane Isaias. This dry air was an important factor that inhibited further intensification of the hurricane off the coast of Florida. SPoRT scientists will continue to participate in the briefings throughout the hurricane season to help identify new applications for NASA data sets in hurricane forecasting.
Earth Observatory Article on Impact to Agricultural Crops in Iowa Following Intense Derecho
Jordan Bell and Christopher Schultz (EaST11) were interviewed for an Earth Observatory article (https://earthobservatory.nasa.gov/images/147154/derecho-flattens-iowa-corn) following the devastating Derecho that moved through Iowa, Illinois, and Indiana on 8/10/20. This derecho flattened wide swaths of near-peak maturity crop land. Their interview comes as both are part of a broader four yearlong Applied Sciences project that is utilizing Earth observations to monitor intense thunderstorms that produce hail damage around the globe. Bell is using satellite imagery from both optical and synthetic aperture radar instruments to analyze damage swaths in agricultural areas. Schultz used lightning rates to track these damaging storms from a satellite perspective providing initial locations to look for damage in Bell’s analysis. Schultz also connected the analysis to key partners with the Iowa State Climatologist Office and the National Weather Service Offices in Des Moines and Davenport to get the initial crop damage assessment to the field.

SERVIR Applied Sciences Team (AST) and SERVIR-Amazonia Hub Working Together to Provide Amazon Fire Forecast to Decision Makers
Doug Morton, a SERVIR AST Principal Investigator for SERVIR-Amazonia, shares the state of the science regarding the upcoming Fire Season in Amazonia in a new NASA article. Morton (NASA Goddard Space Flight Center) leads one of the four AST projects in SERVIR-Amazonia. Each of these projects is developed in collaboration with the SERVIR hub. His project “Forecasting seasonal to sub-seasonal fire and agricultural risk from drought in Amazonia” is producing valuable information to inform decisions makers about fire potential for this year. The fire potential is high due to expected dry conditions for this fire season. The Fire Risk Forecast web page was co-created by Morton and Co-Investigator (Co-I) Yang Chen (University of California, Irvine). SERVIR-Amazonia also organized a webinar at the end of June to share information about the upcoming fire season, where Morton’s Co-I, Niels Andela (University of Maryland, College Park), along with Katia Fernandes from University of Arkansas and Matt Finer from Monitoring of the Amazon Andean Project MAAP shared findings related to fires and their association with recent deforestation, and the appropriate climatic conditions with high potential for fires this year, with decision makers and stakeholders in the region.

Paper on Lightning Mapper Array in Argentina Accepted in Journal of Atmospheric and Ocanic Technology
Timothy J. Lang (ST11) is lead author on a paper, titled “The RELAMPAGO Lightning Mapping Array: Overview and initial comparison to the Geostationary Lightning Mapper," that was recently accepted for publication in the Journal of Atmospheric and Oceanic Technology.
Rich Blakeslee (ST11/Emeritus) and NASA colleagues from the University of Alabama in Huntsville (UAH) and elsewhere also contributed to the study. The paper reports on three-dimensional observations made by a NASA Marshall Lightning Mapping Array (LMA) that was deployed during 2018-2019 in the Cordoba province in north-central Argentina.This region has long been known for producing some of the strongest thunderstorms on Earth, and the LMA made many unique observations of lightning within extreme convection. The new study with the LMA shows that the detection efficiency of the spaceborne Geostationary Lightning Mapper (GLM) varies significantly (between ~30-90%) with thunderstorm evolution and the dominant characteristics of the lightning being produced. RELAMPAGO (Remote sensing of Electrification, Lightning, And Mesoscale/microscale Processes with Adaptive Ground Observations) was the name of the field campaign that the LMA supported (relampago = lightning) in Spanish. The field campaign was focused on intense convection and was primarily funded by the U.S. National Science Foundation (NSF), while the LMA deployment received its funding from the Geostationary Operational Environmental Satellite - R series (GOES-R) Program Office, which supports validation activities for GLM by NASA Marshall.

Marshall Scientists Help Certify New World Records Set for Lightning Size and Duration
Timothy J. Lang (ST11) and Rich Blakeslee (ST11/Emeritus) contributed to the certification of two new World Meteorological Organization (WMO) records for lightning size and duration. The new records - longest flash distance of 440 miles (709 km) and longest flash duration of 16.73 seconds - more than double the previous WMO lightning records from 2017 (which were also co-certified by Lang). The reason is because the spaceborne Geostationary Lightning Mapper (GLM) instrument, with its continuous hemispheric field of view, was used to map these new flash extremes. The flashes occurred in Brazil (October 31, 2018, size) and Argentina (March 4, 2019, duration). The latter flash was also partially resolved by a NASA Marshall Lightning Mapping Array (LMA) deployed to north-central Argentina. Detailed analysis of both flashes, including the comparison with the LMA, can be found in an article titled “New WMO Certified Megaflash Lightning Extremes for Flash Distance (709 km) and Duration (16.73 seconds) recorded from Space,” which was recently published in Geophysical Research Letters found at this link: https://agupubs.onlinelibrary.wiley.com/doi/10.1029/2020GL088888.

NASA and the United States Agency for International Development Sign New Interagency Agreement for SERVIR
On June 30, 2020, the United States Agency for International Development (USAID) and NASA signed a new Inter-Agency Agreement to continue the SERVIR Participating Agency Program Agreement (PAPA) that started in 2005 for another 5 years. This establishes a firm foundation of support from both USAID and NASA to continue SERVIR to the year 2025 and beyond, to “Connect Space to Village” around the world using Earth observation data to improve the lives for many. This agreement provides $12.55 million from USAID to NASA in the next 5 years to continue science coordination support to the five SERVIR hubs, with an additional $5 million potential for related work and funding opportunities. This partnering agreement will strengthen and continue USAID and NASA efforts to apply science and build capacity to use Earth observing satellites and geospatial data, enabling local solutions toward prosperity for developing communities, countries, and regions around the world.
SERVIR Science Coordination Office (SCO) Hosts NASA Webinar on Service Planning Apprach
On June 23, 2020, Emily Adams, Amanda Markert, and Emil Cherrington of the SERVIR SCO led a NASA webinar exchange with engaged members of NASA's Earth Science Division on the topic of Service Planning. Nancy Searby, NASA Capacity Building Program Manager, opened the virtual event and introduced the speakers. As a joint initiative of NASA and the United States Agency for International Development (USAID), SERVIR develops Earth observation-based services through a series of key steps that are expected in international development projects, including developing a Theory of Change; the user consultation and needs assessment process; stakeholder mapping; service design; gender considerations in service design; and monitoring, evaluation and learning. To support SERVIR’s Service Planning approach to designing these geospatial information services, the SERVIR network (including the NASA SERVIR SCO, the SERVIR Support Team from Chemonics, and SERVIR hubs around the world) has developed a Service Planning Toolkit. 63 participants dialed into the webinar, which built on topics originally showcased in 2017 at an event for the SERVIR network (hosted at the SERVIR-Eastern & Southern Africa hub), along with lessons learned from several years of applying the approach at the five SERVIR hubs.
NASA Surface Water Ocean Topography (SWOT) Early Adopter Program Virtual Hackathon
From May 26 to June 1, 2020, the SPoRT project participated in a virtual hackathon for Early Adopters of the NASA Surface Water Ocean Topography (SWOT) mission. The hackathon was designed to engage Early Adopters and help them overcome technical issues in preparing for SWOT data and using the SWOT data simulator. MSFC NPP scientist Nicholas Elmer participated in the hackathon as a presenter and hacker-helper. Elmer contributed to the SWOT data simulator to improve usability by the Early Adopter community and wrote the simulator tutorial used by other Early Adopters during the hackathon. As an Early Adopter, SPoRT is preparing to integrate SWOT observations into the NOAA National Water Model and the SPoRT Land Information System (SPoRT-LIS) product, and has supported the need for low-latency SWOT products to use in operational and near-real-time systems.
Roses Proposal Selected for Funding
Emily Berndt (ST11) in collaboration with Nicholas Elmer (ST11/NPP/USRA) and Gary Jedlovec (ST11 Branch Chief) submitted a proposal to NASA ROSES 2019 Earth Science Research from Operational Geostationary Satellite Systems solicitation to expand previous work to correct and intercalibrate imagery from different satellite platforms which ultimately improves feature identification and detection in multispectral composites. The team members within Short-term Prediction Research and Transition (SPoRT) have a history of developing techniques and capabilities to improve multispectral imagery for the benefit of society and use by operational end users. The proposal “Development of limb-corrected and intercalibrated multispectral composites from the constellation of geostationary satellites" was 1 of 9 selected for funding out of a pool of 83 submissions to NASA. Over the three-year project, the team will refine the previously developed techniques, expand other international geostationary platforms, validate and conduct process studies, and collaborate with NASA Ames to make the improved data available to the broader research community through the GeoNEX data portal. The improved data will additionally benefit SPoRT partners who routinely use multispectral composites – derived from the MSFC Geostationary Operational Environmental Satellite (GOES) receiving station data- in weather forecasting operations.
Marshall Earth Science Disasters Team Collaborating with Partners to Assist with Michigan Floods and Tropical Storm Cristobal
The NASA Headquarters team supporting Earth Science Disasters activities requested a "response" to flooding in Michigan resulting from heavy rains and combined dam failures. Team member Lori Schultz was included as the event lead, helping to coordinate inputs from distributed partners. MSFC team members acquired Landsat and DigitalGlobe Worldview imagery to assist with event analysis, JPL team members contributed their view of flooding from a Planet imagery granule, and external partners provided additional water extent mapping.
An ongoing collaboration with the University of Alabama and Google Earth Engine facilitated an experimental estimation of flood water depth, a new angle and improvement upon other analysis techniques to date. Information is being shared with partners at FEMA HQ to support their interests and involvement in flood response activities.
Lori Schultz is also currently serving as the “event lead” for activities regarding the recent Tropical Storm Cristobal impacts to the Gulf Coast. As the event lead, she has been participating in routine organizational calls with the Disasters Team. However, the coastal/rainfall-based flooding has been less severe than anticipated and no major actions were taken in response.
New Book, “Satellite Precipitation Measurement, Vol 2”, Features Chapters by SRPD Deputy Manager, Walt Petersen
“Satellite Precipitation Measurement, Vol 2” has recently been published by Springer and features chapters authored or co-authored by Walt Petersen, Deputy Manager of the Science Research and Projects Division. Over the last two decades, there have been significant advances in the measurement of precipitation from space, primarily due to the Tropical Rainfall Measuring Mission (TRMM), the Global Precipitation Measurement (GPM), CloudSat, and a constellation of satellites hosting passive microwave sensors. This book provides a complete overview.
Walt Petersen led the chapter on “GPM Ground Validation” (Chapter 26), describing the GPM Ground Validation program, its international contributions, instrumentation, and science results. The chapter also focuses on describing observed characteristics of precipitation (e.g., 3D structure of precipitation from the surface to the tropopause, precipitation phase, drop-size distributions, rain and snowfall rates etc.) and how these characteristics compared to GPM satellite-based remote sensing estimates.
He also co-authored a second chapter (Chapter 31), “Integrated multi-satellite evaluation for the Global Precipitation Measurement mission: Impact of precipitation types on spaceborne precipitation estimation.” This chapter describes new state of the art radar network-based products developed in collaboration with NOAA, unique ways to use those products to compare ground and satellite-based estimates of precipitation, and how those comparisons vary as a function of the precipitation regimes and their physics.
“Satellite Precipitation Measurement” is a two volume work and more information can be found at https://www.springer.com/us/book/9783030357979.

Marshall's Earth Science Branch Supports Multiple COVID-19 Efforts
On May 29, 2020, the Inter-Agency Implementation and Advanced Concepts (IMPACT) team, in collaboration with Amazon Web Services (AWS), made the following datasets (Ozone Monitoring Instrument NO2, MODIS Vegetation Indices and MODIS Aerosol Optical Depth) available in Cloud Optimized GeoTIFF (COG) format for the COVID-19 Space Apps Challenge. COG allows data to be dynamically analyzed in efficient ways.
The global hackathon held on May 30 - 31, 2020 invited teams to use Earth observation and other open source data to formulate solutions to challenges related to the COVID-19 pandemic. NASA and AWS have a space act agreement in place to explore best practices around discovery, access, and use of high-value NASA science datasets. Making these products freely available for the virtual event showcased the partnership and emphasized our efforts in making analytics-optimized data stores available to the science community. More information about the datasets and access can be found at https://earthdata.nasa.gov/collaborate/cloud-optimized-geotiffs. These datasets were also ingested into the Euro Data Cube along with datasets from Japan Aerospace Exploration Agency and European Space Agency.
NASA also hosted a special edition of the Space Apps Challenge to invite participants to develop analyses on the COVID-19 global pandemic using NASA observations. Andrew Molthan participated as a subject matter expert for the “Light the Path” challenge, where participants were to use nighttime light and other observations to try and track changes in human behavior as a result of the COVID-19 pandemic. Molthan participated remotely with global (remote) participants to provide guidance and suggestions on how to incorporate NASA data, including processing of imagery and opportunities to combine nighttime lights, surface remote sensing, population, and other data to help address questions of interest. Later this summer, Andrew and other NASA colleagues will have an opportunity to judge the final submitted projects and select multiple winners.
Green Team Presentation on COVID-19 Impacts to Climate
At the June meeting of Marshall’s Green Team, Gary Jedlovec presented insight on the potential impact of Covid-19 on climate change. The industrial slowdown resulting from the COVID-19 pandemic has led to a 25-30% reduction in global daily carbon dioxide emissions (~20 MegaTons CO2 / day) for the months of March-May 2020. Despite what seems to be a significant drop in emission, this has yet to show any reduction in the upward annual trend observed in carbon dioxide over the last 80 years.
However, satellite observations of nitrogen dioxide, a key component of air pollution (particles around 2.5 micrometers in size) and highly correlated with burning of fossil fuels, show large reductions over cities compared to pre-COVID-19 amounts. This reduction has led to less pollution, increased visibility, and lower health risks for respiratory problems in these regions. NASA and other agencies around the world have increased funding efforts to further explore the impact of the pandemic on the environment. Marshall’s Green Team supports Marshall’s environmental policy to enabling NASA’s mission by providing environmental compliance and stewardship and a safe, healthful workplace with its actions and educational outreach activities. Jedlovec supports the Green Team related to climate components of NASA’s Strategic Sustainability Performance Plan (SSPP).
Lightning Research Flashes Forward
This article highlights the collaboration between NASA SPoRT and the National Weather Service in Huntsville for severe thunderstorm warning decisions in December 2019 and January 2020 in the Tennessee Valley. Schultz also spoke of the lightning safety initiatives within SPoRT for the improvement in public safety. SPoRT’s work with lightning initiated wildfires was also highlighted to demonstrate how SPoRT is working to identify lightning initiated wildfires in real-time. This article included other key researchers who work with the Lightning Group at MSFC and SPoRT, like Ryan Said at Vaisala, lightning safety experts Ron Holle and May Ann Cooper, lightning researcher Bill Rison at New Mexico Tech University, and NWS Huntsville warning forecaster Ashley Ravenscraft.
SERVIR Analysis Using NASA Satellite Data Demonstrates Effectiveness of U.S. Government Investments in Ethiopia.
NASA satellite data analysis conducted by the SERVIR Science Coordination Office demonstrated the success of a decade of water-related investments (e.g., dam and diversions) supported by the US Agency for International Development’s (USAID) Food for Peace projects in Ethiopia.
For instance, USAID’s Office of Food for Peace has supported community-level resilience-building activities in eastern Tigray, Ethiopia, including the construction of water management infrastructure, through the Government of Ethiopia-led Productive Safety Net Program (PSNP). A recent analysis used 34 years of satellite data (1984-2018) to explore changes in land productivity and water availability associated with the construction of this infrastructure at 36 sites in eastern Tigray. SERVIR’s analysis of NASA satellite observations found that:
- Project sites show increased water availability throughout the year.
- Increased water availability persists in drought years.
- In most sites, water infrastructure interventions likely strengthened resilience by improving water access during the main cropping season.
- In some areas, water infrastructure interventions have also strengthened resilience by allowing for a second crop to be planted.
USAID invests billions of dollars in support of country initiatives around the world, with an aim of promoting US diplomacy initiatives. Without satellite data and analysis, it is often difficult to show results of these investments at the landscape scale. SERVIR’s analysis was applauded by USAID senior leadership and is published in different formats (Agrilinks article and video). NASA is currently training SERVIR hubs to perform similar analyses to replicate the methodology in other countries.
SERVIR Science Coordination Office Supports Virtual Training on Monitoring of Mangroves
Andrea Nicolau, Kelsey Herndon, and Africa Flores-Anderson of the SERVIR SCO supported the virtual training “Mapping and monitoring changes in mangrove forests using Python and more”, led by Marc Simard (NASA JPL) twice a week from 5/14/20 to 6/8/20. The training was the second provided as part of Simard’s subject matter expert work to support the systematic monitoring of mangroves in Guyana. The eight online sessions used cloud-computing resources provided by Amazon Web Services (AWS) and the Amazon Sustainability Data Initiative (ASDI) that served as a time-saving alternative to working with big data and complex software in an online setting. Objectives of the training included producing basic map products with Synthetic Aperture Radar (SAR) data for a monitoring system and documenting the production methods so they can be replicated on an annual basis. The virtual workshop also included the participation of Temilola Fatoyinbo and her team from NASA GSFC as guest presenters to leverage the use of Google Earth Engine for the mapping and monitoring of mangroves.
The nineteen participants included individuals from the University of Guyana (UoG), National Agricultural Research and Extension Agency (NAREI), Conservation International (CI), Guyana Forestry Commission (GFC), National Drainage and Irrigation Authority (NDIA), Amerindian Peoples Association (APA), Conservation International (CI), World Wildlife Fund (WWF), Hydrometeorological Service, Environmental Protection Agency (EPA), the Ministry of Natural Resources, Guyana Lands and Surveys Commission (GLSC), and the Ministry of Public Infrastructure – Sea and River Division.
Paper on Weather Model Assimilation of CYGNSS Wind Observations Published in Remote Sensing
Timothy J. Lang is a coauthor on a paper, titled “A Study on Assimilation of CYGNSS Wind Speed Data for Tropical Convection during 2018 January MJO,” that was recently accepted for publication in the journal Remote Sensing.
The study, led by NASA colleagues at the University of Alabama in Huntsville (Xuanli Li and John Mecikalski), tested the assimilation of Cyclone Global Navigation Satellite System (CYGNSS) wind observations, along with other datasets, into a weather forecast model. This is one of the first studies to test the assimilation of CYGNSS winds for forecasting tropical weather other than just tropical cyclones, as the focus was convection that occurred during an active Madden-Julian Oscillation (MJO). The MJO is a tropical weather pattern that can have global impacts, and CYGNSS may help improve our understanding of the MJO, because compared to traditional scatterometers CYGNSS wind observations are less sensitive to heavy rainfall that occurs during active MJOs. The study found that CYGNSS did indeed lead to improvements in weather forecasts during the MJO, especially for winds. However, even better forecast improvement occurred when other global wind and precipitation datasets were ingested as well. This study shows the added value of CYGNSS data for tropical weather forecasting, when used as part of a holistic data assimilation approach.

SERVIR-Amazonia and the UN Food and Agriculture Organization Host Virtual Training on Sample-Based Area Estimation
Africa Flores-Anderson, Kelsey Herndon and Andrea Nicolau of the SERVIR Science Coordination Office (SCO) supported a virtual training on “Sample-Based Area Estimation and Accuracy Assessment”. This was a joint workshop between SERVIR-Amazonia and FAO. Trainers included Ms. Paula Paz from the Alliance of Bioversity International and the International Center for Tropical Agriculture (CIAT), Ms. Milagros Becerra from Conservacion Amazonica – ACCA , Mr. Erith Muñoz from FAO and Ms. Africa Flores-Anderson from SERVIR SCO. The objective of the training was to strengthen the capacity of technical staff from the Ministry of Environment and Water of Ecuador (MAE) to perform their area estimations and accuracy assessment using state-of-the-art methods that help them mitigate omission errors found in their forest maps. Eleven staff members from MAE participated in the training. Free and open-source Open Foris platforms, including SEPAL and Collect Earth Online (CEO) were used. MAE is currently working to produce its carbon emission estimates for the 2018-2019 period to access their results-based payment for reduced deforestation for the third time. This ongoing collaboration with SERVIR-Amazonia and FAO will contribute to MAE´s goals to effectively estimate emissions reduction and enroll in results-based payments in order for communities to sustain their conservation efforts.
SERVIR Subject Matter Expert-Led Training on Mapping Forest Degradation with Synthetic Aperture Radar
Kelsey Herndon, Andrea Nicolau, and Africa Flores-Anderson of the SERVIR Science Coordination Office (SCO) supported the virtual training “Mapping Forest Degradation with SAR Sentinel-1 Time Series”, led by Josef Kellndorfer (EarthBigData). The training was the third provided as part of Dr. Kellndorfer’s subject matter expert work to support the expansion of SAR to existing forest monitoring platforms in SERVIR-Amazonia (SAMZ) partner organizations. Objectives included implementing various degradation algorithms using Sentinel-1 time series data in Jupyter Notebooks, testing the effectiveness of the algorithms for identifying known degradation sites, and developing appropriate recommendations on which methods to use to identify forest degradation in an operational manner. This training was one in a series of SAMZ trainings that took place virtually instead of in person, due to restrictions related to the COVID-19 outbreak. Virtual machines for all participants were made possible with the support of Amazon Web Services (AWS) and the Amazon Sustainability Data Initiative (ASDI). The twenty participants included individuals from Asociación para la Conservación de la Cuenca Amazónica (ACCA), Centro Internacional de Agricultura Tropical (CIAT), Instituto de Hidrología, Meteorología y Estudios Ambientales (IDEAM), Instituto de Manejo e Certificação Florestal e Agrícola (Imaflora), Instituto Chico Mendes de Conservação da Biodiversidade (ICMbio), Amazon Conservation Team (ACT), Universidad del Rosario, Instituto Brasileiro do Meio Ambiente e dos Recursos Naturais (IBAMA), and Instituto Socioambiental (ISA). The technical skills developed in this workshop will feed directly into the forest monitoring efforts of SAMZ partner organizations to improve forest degradation monitoring across the region.
SERVIR-MEKONG Activities Highlighted by United States Ambassador to Thailand
On April 25, 2020 U.S. Ambassador to Thailand, Michael George DeSombre, wrote an op-ed in which he mentioned NASA and the United States Agency for International Development (USAID) activities through SERVIR-Mekong that bring publicly available satellite data to the region to help local governments address challenges of drought, flooding and transboundary water resources. He particularly highlighted the Drought Early Warning portal that SERVIR-Mekong has co-developed with the Mekong River Commission (MRC). This online portal, launched in March, uses drought and crop yield forecasts generated by the Regional Hydrologic Extremes Assessment System (RHEAS) modeling framework. The SERVIR Science Coordination Office at NASA Marshall Space Flight Center is leading the development of the RHEAS framework, along with scientists at NASA Jet Propulsion Laboratory (JPL). The MRC distributes weekly and monthly Drought Early Warning bulletins through the portal, and monitors drought conditions for the countries in the Lower Mekong Basin as part of their drought management strategy.

Earlier the same week, the Michael Barkin, Senior Policy Advisor to US Mission to the UN, mentioned SERVIR in talking points for the April 22, 2020 United Nations Security Council video teleconference on Climate Change and Security Risks, as an example of the United States working with global partners to share knowledge, data and tools.
