We're planning to retire the Community Data Portal (CDP) after nearly 15 years of service. The most active datasets will be migrated to the Climate Data Gateway website. We tentatively plan to shutdown the CDP service by Jan 1, 2018. Please contact us with questions or concerns.
 
 
Thermospheric General Circulation Models (TGCM)
Summary: The NCAR 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.

Recent models in the series include a self-consistent aeronomic scheme for the coupled Thermosphere/Ionosphere system, the Thermosphere Ionosphere Electrodynamic General Circulation Model(TIEGCM), 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, the Thermosphere Ionosphere Mesosphere Electrodynamic General Circulation Model (TIME-GCM).
