The Geospace Environment Modeling (GEM) program is a [http://www.geo.nsf.gov/atm/start.htm| National Science Foundation (NSF) Division of Atmospheric Sciences] initiative to coordinate and focus research on the near-earth portion of geospace from the lower ionosphere to where the earth system interacts with the solar wind. The purpose of GEM program is to support basic research into the dynamical and structural properties of geospace, leading to the construction of a global geospace general circulation (GGCM) model with predictive capability. The GGCM effort is now being treated as a separate campaign. The strategy for achieving GEM goals is to undertake a series of campaigns, in both theory and observational modes, each focusing on particular aspects of the geospace environment. Beginning in 1991 and continuing through about fiscal year 1996 the first campaign focused on the magnetospheric cusp and boundary layer. The second campaign on the magnetotail and substorms ran from 1994-2003. Now underway are the third campaign on the inner magnetosphere and fourth campaign on the Magnetosphere-Ionosphere Coupling.

Geospace Environment Modeling (GEM) Image:Nsf.gif

Geospace Environment Modeling (GEM) is a broad-based, community-initiated research program on the physics of the Earth's magnetosphere and the coupling of the magnetosphere to the atmosphere and to the solar wind. The purpose of the GEM program is to support basic research into the dynamical and structural properties of geospace, leading to the construction of a global Geospace General Circulation Model (GGCM) with predictive capability. This GGCM model will be modularized and will complement parallel developments of magnetohydrodynamic models. The strategy for achieving GEM goals is to undertake a series of campaigns, in both theory and observational modes, each focusing on particular aspects of the geospace environment.

The Geospace Environment Modeling (GEM) program is sponsored by National Science Foundation (NSF) Division of Atmospheric Sciences.
