Energetic particle radiations measured by particle detector on board CBERS-1 satellite

摘要: Using the data measured by energetic particle detector on board CBERS-01 and-02 for past five years, statistics was made to show general features of MeV electrons and protons along a solar synchronous orbit at an altitude 780 km. This height is in bottom region Earth’s radiation belts. Detectors are inside satellite cabinet such continuous monitoring environment has seldom conducted so far. After proper careful treatment, it indicated that well correlated with outside. Besides agreement distribution characteristics similar observations from other satellites, attention particularly paid disturbed conditions. Variations fluxes closely related proton events, general, electron outer belt Dst index after three days’ delay while injection occurred almost same day during great magnetic storms. It confirmed both appear Polar Cap only events.
