Ready
to fly through the ionosphere? W. Kent Tobiska, president
of Space Environment Technologies, offers these simple instructions:
"One,
download and install Google
Earth."
"Two,
visit our web
site and click on the link 'Total Electron Content.'"
Wait
for the file to load and presto—you're flying through the
ionosphere. A typical screenshot looks like this:
In
addition to total electron content, the 4D model also can
be configured to display available radio frequencies, maximum
usable frequencies, and the critical "bounce frequency"
of the ionosphere's f2-layer—terms well known to hams and
other experts. The corresponding files are all available at
the CAPS
web site.
