Title: Modeling Radiation Belt Electron Dynamics with the DREAM3D Diffusion Model

Abstract

The simulation results from our 3D diffusion model on the CRRES era suggest; our model captures the general variations of radiation belt electrons, including the dropouts and the enhancements; the overestimations inside the plasmapause can be improved by increasing the PA diffusion from hiss waves; and that better DLL and wave models are required.
