Geospace Environment Modeling (GEM)

The Geospace Environment Modeling (GEM) program is a broad-based research program focused 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 models of the geospace environment with predictive capability. The long-term goal of the GEM program is advancing numerical simulations of geospace that describe the global dynamics of the magnetosphere and how the magnetosphere interacts with the solar wind and the ionosphere. Advancing modeling capabilities includes metrics and validation, developing both first-principles and empirical models, as well as promoting the broader use of these models by the geospace community. The program is committed to developing the next generation geospace researchers and submissions from early career scientists are encouraged. The program supports an annual workshop held for one week each summer to provide a forum for investigators to present and discuss recent results, exchange information, plan future experiments, and improve and develop geospace modeling capabilities.
