“Daunting” task of assembling data for a geospace global circulation model begins



This is the second article in a series of three on the Geospace Environment Modeling program. The first article, “Milestones in Geospace Environment Modeling,” appeared in the December 28, 1993, issue of Eos.

The Geospace Environment Modeling (GEM) Program is quickly moving toward a general circulation model (GCM) for geospace similar to the powerful GCMs that now support troposphere-stratosphere and thermosphere-ionosphere research. Since, according to Richard Feynman, “the test of a science is its ability to predict,” the geospace GCM (GGCM) holds the key to validating magnetospheric science, unifying its researchers, and demonstrating the mastery of the field to other geophysicists.
