Abstract:
We have analyzed the trapped electron data (0.19-3.2 MeV) taken by the Japanese OHZORA satellite operated at 350-850 km altitude in polar orbit during 1984-1987 near solar minimum. The electron observations reveal all the global attributes of the quiet-time electron radiation belts, such is the South Atlantic Anomaly, the electron "slot", and the outer radiation belt regions. The electron data are in general agreement with the NASA AE-8 electron model, but there are differences, particularly with respect to distinctive local-time variations in the slot region. In this paper, we present results from analyses of variations of the electron pitch angle distributions with local time, L-shell and altitude.
