- Purpose:
-
The energetic plasmas in radiation belt have deleterious impact on satellite
systems and humans in space. It is critical to predict and forecast the
developments of these energetic particles and provide warnings early enough for
appropriate actions to be taken. Fok, Khazanov, and co workers' radiation belt and ring current model is
a data-driven physics-based model which solves the convection-diffusion equation of
plasma distribution functions in the range of 2-10 Earth radii. The only inputs to
the model are solar wind and interplanetary magnetic field (IMF) conditions. The
model calculates energetic plasma fluxes (10 keV to 5 MeV for electrons, 10 keV to
1 MeV for H+) and the correspoinding radiation doses. The current version of the
model provides now-casting of the radiation-belt environment. Our ultimate goal
is to do predicitons 24 hours ahead of time. On the right is an example of the RBE
output. The left panel is the pitch-angle averaged flux at the magnetic equator. The white
circle is the geosynchronous orbit. The right panel shows the pitch-angle distribution.
- Input:
-
IMF, solar wind density, velocity, and predicted Dst.
- Output:
-
The output of the Radiation Belt Environment model is an ASCII file containing electron
or proton fluxes as a function of time, location, energy and pitch angle as well as plots
of the plasma differential flux at the magnetic equator and the pitch-angle anisotropy(PAA).
