SUMMARY:Modelling Earth’s Electron Radiation Belts - Johannes Sadler (DA
 MTP)
DTSTART:20251105T140000Z

CONTACT:Thomas Jannaud
DESCRIPTION:Earth’s radiation belts consist of relativistic electrons an
 d ions trapped in the geomagnetic field. Radiation belt electrons can dama
 ge satellites\, so it is important to develop accurate forecasts of the ra
 diation belts. The British Antarctic Survey Radiation Belt Model (BAS-RBM)
  was developed to study the time-dependent electron fluxes in the radiatio
 n belts\, and has been adapted into a forecasting model. This talk present
 s work from the first year of my PhD\, focusing on improving BAS-RBM simul
 ations of large geomagnetic storms. The talk will describe how gyro-resona
 nt wave-particle interactions are modelled as diffusion of the velocity di
 stribution function\, and present some improvements to the diffusion rate 
 calculations. The talk will also discuss the possible role of the plasmasp
 here in radial transport in the radiation belts.
