Abstract:
The St. Patrick’s Day storms of 2015 and 2013 present us with a textbook opportunity to study the evolution of the response of the thermosphere and ionosphere to a geomagnetic storm. The intervening year, 2014, was very quiet during this mid-March time period. We have then, the opportunity to test our ability to reproduce these disturbed conditions.

We will present the SSUSI observations of the ionospheric conditions and response and compare this to the results from IDA4D assimilation results. The high latitude energy inputs are provided by the SSUSI F16, F17, F18 and F19 spectroscopic imagers. We can also examine the TIMED/ GUVI data during these selected time periods and investigate the O/N2 and NO response.

Just 3 of the hundreds of orbits of data are shown in the figure. Note that we provide a wide range of products on the SSUSI and GUVI wewb pages.
