Fok Radiation Belt Electron (RBE)

The Fok Radiation Belt Model (FRC) 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.

Model Description
The Fok Radiation Belt Model (FRC) 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.

Model Input

  • 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)

Model Output
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.
