DESCRIPTION:The flux of relativistic electrons in Earth's radiation belts 
 is highly variable\, fluctuating over orders of magnitude within hours. In
  particular\, the flux at the outer edge of the magnetosphere may undergo 
 rapid and sustained losses due to magnetopause motion. Forecasting the beh
 aviour of the radiation belts is important in order to predict the risk po
 sed to satellites by high energy particles. We use a three-dimensional dif
 fusion model based on the Focker-Planck equation to model phase-averaged p
 hase space electron densities to investigate the behaviour of the outer ra
 diation belt. We investigate the accuracy of a last closed drift shell mod
 el in predicting electron fluxes near the magnetopause\, with the eventual
  aim of using this model to replace the data-driven outer boundary of the 
 diffusion model.
