Reproducing Ultra-Relativistic Electron Acceleration Using a Coupled Density and Radiation Belt Model
The density of low energy charged particles trapped in Earth's magnetic field can influence how higher energy trapped electrons are affected by natural radio waves within the magnetic field. We describe a modification of the British Antarctic Survey Radiation Belt Model that includes a model of density that varies in both time and space. These density values are used to drive a statistical model of electron scattering due to chorus waves. We demonstrate that including the variance of density in the model recreates the acceleration of electrons up to ultra-relativistic energies better than other previous approaches to accounting for the low energy charged particle density.
