Paper Accepted for Publication in Journal of Geophysical Research

William Koshak (ST11) is co-author on an article recently accepted for publication in Journal of Geophysical Research - Atmospheres, with title “Observations of Lightning NOx Production from GOES-R Post Launch Test Field Campaign Flights”. The Geostationary Operational Environmental Satellite R-series Post Launch Test (GOES-R PLT) Field Campaign was conducted in spring 2017.  GOES-16 Geostationary Lightning Mapper (GLM) observations were compared with aircraft-based column measurements of NO2 (nitrogen dioxide) derived from the NASA Goddard Geo-CAPE Airborne Simulator (GCAS).  Specifically, the NO2 columns from GCAS and the GLM data were used to estimate the moles of NOx produced per lightning flash for ten convective systems over the US and western Atlantic regions.  It was estimated that NOx production by lightning over the US is approximately 360 moles per flash, and that the NOx production per flash is positively correlated with flash multiplicity and optical energy but negatively correlated with flash density.
