AB: The Global Ionosphere Thermosphere Model (GITM) is used to simulate the response of the thermospheric density during several different solar flare events. Data from the SEE instrument onboard TIMED is used in GITM to specify the solar EUV flux. The model results run with and without high-latitude drivers are compared to mass density data from the Champ satellite in order to isolate and quantify the contribution from the excess solar energy. In addition, we will investigate the speed and uniformity of propagation of gravity waves created by the solar flares.
