    Abstract
  • The new generation of Space Environment Monitor (SEM), SEM-II, onboard the Chinese meteorological satellite, FengYun-3E, has the ability to measure the charged particle flux with particle energy from 30 eV to 300 MeV in multi-directions, the satellite surface potential, the radiation dose in sensors, and the geomagnetic field variations. The space environment detections derived from SEM-II can be utilized for satellite security designs, scientific studies, development of radiation belt models, and space weather event monitoring or disaster warning. In this paper, we introduce the SEM-II’s instrument characteristics, interpret the in-orbit calibration algorithm, perform the quantitative test to check the particle and the magnetic field detections’ biases by the cross-calibration methods, and do the qualitative tests to check whether the radiation dose and the surface potential detections follow the nature law of space environment by comparing with the historical records. The results show that the uncertainties of the particle detections are less than 20%, the uncertainties of the magnetic field detections are about 1%, the radiation dose and the surface potential detections coincide with the historical records and the space environment knowledge. The instruments’ responses to the space weather events are also presented.
