Fok Radiation Belt Electron
Version: 1.0The Fok Radiation Belt Model (RBE) is a bounce-averaged kinetic model of the radiation belt electrons. This model calculates the temporal and spatial variation of the phase space density of radiation belt electrons(e-), in the energy range of 10 - 4000 keV. The model considers particle drift, charge exchange loss, in realistic, time-varying magnetic and electric fields. The simulation region is from the dayside magnetopause to the nightside boundary at 10 earth radii. The model is an initial-boundary-value problem, so initial distribution and boundary distribution as a function of time is required to run the model.

Inputs
3D Magnetic Fields (from SWMF GM/BATSRUS model) 2D Ionospheric height-integrated Potentials (SWMF IE/Ridley model) Equatorial Plasma Density (SWMF GM/BATSRUS) Equatorial Plasma Temperature (SWMF GM/BATSRUS)
Outputs
Equatorial e- fluxes as functions of time, energy and pitch angle. Fluxes at off-equator can be obtained by assuming constant flux along a field line.
Model is time-dependent.
