AB: The period of post-solar maximum geomagnetic storms in October and November 2003 were some of the largest storms ever recorded. The thermospheric and ionospheric responses have been simulated using the NCAR TIMEGCM. The model shows large areas of O/N2 depletion spreading from high latitudes, and corresponding reductions in the ionospheric electron density. The model is used as a framework to interpret some of the compositional effects observed by the GUVI instrument on the TIMED satellite, and corresponding ionospheric total electron content. We explore how the I-T system responds to the development and subsidence of geomagnetic storms, and we describe some of the important physical processes that will affect planning for the utilization of measurements from the Geospace investigations in NASA's Living With a Star Program. The study also illustrates the value of measuring both the neutral and ionized gases, of obtaining quasi-global views from imaging instruments, and the synergy between satellite data, ground-based measurements, and models.
