We have combined two well developed models, the Comprehensive Ring Current Model (CRCM) and the Radiation Belt Environment (RBE) model to form a Comprehensive Inner-Magnetosphere Ionosphere (CIMI) model. CIMI predicts ion and electron fluxes in the radiation belts and ring current, particle density in the plasmasphere, Region 2 current, subauroal electric field and particle precipitation in the ionosphere, and their responses to solar wind condition. CIMI considers important cross-energy interactions in the inner magnetosphere and is able to identify the physical processes that are responsible for ring current, radiation belt enhancements and losses, such as, particle injection, adiabatic acceleration, wave-particle interactions and magnetopause shadowing. We demonstrate the capability of CIMI by simulating a magnetic storm on 5-9 April 2010 and a MHD substorm. We also illustrate that CIMI is an excellent tool for analyzing and interpreting global energetic neutral atom data from TWINS and the in-situ measurements from the Van Allen Probes mission.
