abstract. Radiation belt dynamics is one of the well known but still unsolved issue of solar terrestrial physics. This is also important for the practical point of view because relativistic electron can penetrate into a satellite body and causes deep dielectric charging. This phenomena is one of the major reason of satellite anomaly. We start developing the prediction of relativistic electron environment using numerical simulation with observation data. The data can be used as some background conditions and also for the empirical parameters, such as diffusion coefficient. We can monitor wide-regions of ULF activities using SuperDARN and ground-based magnetometer data. The plan of predicting relativistic electron environment using numerical simulation with observation are introduced in our talk.
