Abstract:
Since its launch on-board the satellite FY-3A in May 2008 and FY-3B in November 2010 separately, the space environment instrument is collecting data on trapped protons with energy 3 MeV ~300MeV and electron with energy 0.15MeV~5.7 MeV. The satellites were launched on a 98 degrees inclination solar orbit with altitude 830 km. The paper presents the observations of dynamics of charged particle with different energy performed from May 2008 until May 2014. The cross-calibration methodologies of high energetic particle data between FY-3 satellites and NOAA satellites will briefly be described, followed by the presentation of results obtained from the instruments in space. A case study of 2.5~6.9MeV protons and 0.3~1.1MeV electrons between FY-3B and NOAA-17 satellite based on possibly physical conjunctions shows that there are some systematic differences in FY-3B measurements when compared to NOAA-17 data. Quite good consistence between the satellite measurements after cross-calibration can be obtained. This effort should be useful for data application from multi-satellite missions.
