Measurements of ozone within the geographic region irradiated by the electrons (magnetic latitudes between 55° and 60°) were extracted from the CDHF database. Fortran and IDL programs were then used to analyze and plot the data in various ways. The most useful analysis was to order the data in local solar time and look for deviations from the diurnal cycle.
Results of the analysis have been presented at meetings of the
American Geophysical Union and the
1997 CEDAR Workshops.
A paper discussing these results appeared in the Journal of Geophysical Research, 104, 165-176, 1999.
The data discussed at the 2001 NSREC are available here.

Below are examples of the electron flux that affects the atmosphere (precipitating) and spacecraft (trapped).
