AB: A model of magnetic and electric perturbations in the Ultra Low Frequency (ULF) wave regime is used to simulate in a realistic way the radial diffusion of radiation belt electrons. The field model is based on the assumption that compressional oscillations propagate from the magnetopause into the inner magnetosphere and are reflected at 1 RE. The electrons are traced for various levels of magnetospheric activities. Through the diffusion in the electrons' orbits we determine the radial diffusion coefficients corresponding to different levels of ULF waves; the calculated diffusion coefficients are consistent with theoretical calculations. Finaly, the response of constructed electron fluxes as measured by a virtual satellite to the field perturbations is monitored.
