Scientific paper
During October-November 2003, a series of large coronal mass ejections and solar flares caused significant changes in the terrestrial upper atmosphere and ionosphere. We have simulated these effects using the NCAR Thermosphere-Ionosphere-Electrodynamics General Circulation Model (TIE-GCM). Solar photon inputs to the model were obtained from solar irradiance instruments on the TIMED and SORCE satellites, and auroral forcing obtained using the AMIE procedure. This study enables quantification of the relative importance of photon and auroral forcing of ionosphere/thermosphere density and temperature. Ion density enhancements and airglow intensities derived from the model results can be compared to observations to investigate the simulation fidelity during these extraordinary events.
