Brief description: The Thermospheric General Circulation Models (TGCM's) are three-dimensional, time-dependent models of the Earth's neutral upper atmosphere. The models use a finite differencing technique to obtain a self-consistent solution for the coupled, nonlinear equations of hydrodynamics, thermodynamics, continuity of the neutral gas and for the coupling between the dynamics and the composition. The Thermosphere Ionosphere Electrodynamic General Circulation Model (TIEGCM) is a recent model in the series, which include a self-consistent aeronomic scheme for the coupled Thermosphere/Ionosphere system and an extension of the lower boundary from 97 to 30 km, including the physical and chemical processes appropriate for the Mesosphere and upper Stratosphere.
