Cross-calibration of high energetic particles data—A case study between FY-3B and NOAA-17

Cross-calibration of high energetic particle data is a primary requirement for the availability of multi-instrument, multi-spacecraft data. It also can provide a method to verify relative reliability of data from single satellite measurement. This paper presents a case study of energetic particles data cross-calibration between FY-3B and NOAA-17. A generally good agreement is acquired in the flux values and distribution trend of 2.5–6.9 MeV protons and 0.3–1.1 MeV electrons between FY-3B and NOAA-17 satellites. It suggests that the data observed by FY-3B is properly cross-calibrated. We can also confirm that energetic particles data observed by FY-3B satellite is available.
