Sun-to-Earth Modeling
Models involving the fully connected Sun-to-Earth system make it possible to simulate geomagnetic activity caused by solar activity with one code.

• Center for Space Environment Modeling (CSEM)
  Interdisciplanary research institute at the College of Engineering at the University of Michigan sponsored by MURI developing computational models of near-earth space weather.
• SolarCISM
  The Center for Solar Weather Modeling is an NSF-sponsored Science and technology Center (STC) aiming to develop a model of the conditions in space between the Earth and Sun based on solar activity. The goal is to provide a model that can be used for space weather analyses and forecasting.

Coronal Modeling
3D MHD models of the corona will help link IMPACT solar wind measurements to the Sun.
