During October-November 2003, a series of large coronal mass ejections and solar flares caused significant changes in the terrestrial upper atmosphere and ionosphere. Using measurements from solar irradiance instruments on the TIMED and SORCE satellites to drive the NCAR Thermosphere-Ionosphere-Electrodynamics General Circulation Model (TIE-GCM), we show preliminary results of the effects of these events on the ionosphere, and quantify the relative importance of photon and auroral forcing of thermospheric density and temperature.
