The ring current, plasmasphere, and auroral systems will be imaged using energetic neutral and ultraviolet cameras. These imagers will return line-of-sight integrated images of these optically thin plasmas, which will require careful analysis in order to recover full three dimensional character of these magnetospheric systems. The IMAGE Mission will also include the Radio Plasma Instrument. This instrument will use radio waves to quantitatively probe magnetosheath, plasmasphere, and magnetosphere densities. An overview of the IMAGE Theory and Modeling Team work will be presented. The Team has adopted the magnetic cloud event of October, 1995, for a simulation study. A single, modeled magnetospheric system is being developed for the purpose of simulating all instrument products. Instrument products and image analysis techniques to be applied to those products are being developed and will be discussed.
