The work relates to the preliminary development of a comprehensive, multi-level, 3-D magnetohydrodynamic model that seeks to describe the detailed, global interaction of the solar wind plasma and magnetic field with the Earths geospace. The development of five separate advanced computational submodels of the complete interaction model involves approximately 42,000 lines of fortran source code. These submodels provide the capability for quantitatively simulating a variety of steady and unsteady phenomena associated with the solar wind-terrestrial environment interaction process to a degree previously unattainable. A number of these new developments have been incorporated into a core interaction submodel that can be structured to work in both a rapid warning mode for spacecraft protection as well as in a detailed scientific analysis mode for fundamental studies. The other submodels developed either simulate similar phenomena of the solar wind-terrestrial environment interaction process as the core interaction submodel but at a higher level of simulation accuracy or simulate additional interaction phenomena.
