Model Description
The Comprehensive Inner-Magnetosphere Ionosphere (CIMI) model is a bounce-averaged kinetic model of the ring current and radiation belts. This model calculates the temporal and spatial variation of the phase space density of ring current and radiation belt species: H+ and O+ in the energy range of 0.1 - 400 keV and electrons (e-) in the energy range of 1 - 4000 keV. The model considers particle drift in realistic, time-varying magnetic field, and self-consistnet electric field that is solved taking into account current closure in the ionosphere. CIMI also considers charge exchange loss, energy and pitch-angle diffusion due to whistler mode chorus waves and plasmaspheric hiss. The simulation region is from the dayside magnetopause to the nightside boundary at 10-15 earth radii. The model is an initial-boundary-value problem, so initial distribution and boundary distribution as a function of time are required to run the model.
