ملخص

The Space Environment Monitor (SEM) aboard the FY-3C satellite monitors energetic particles, including protons, electrons, and heavy ions, and the radiation dose and surface potential of the satellite caused by the particles. The independent data on the energetic particles of the FY-3C satellite are essential in space weather operation. Quantitative evaluations of such data are conducted to examine their validity. Cross comparisons are performed with similar satellite data to evaluate the energetic particle data of the FY-3C satellite. Normalization is performed based on the basis of certain assumptions to eliminate the differences caused by observation time, location (longitude and latitude of the sub-satellite point, and satellite height), orientation, and energy range. Statistical parameters such as correlation coefficient, slope, and standard deviation are calculated to evaluate the consistency between the compared data. The cross comparison of the FY-3C data with the NOAA-18 and FY-3B data during a quiet space weather period shows that the energetic particle data of the FY-3B satellite are consistent with the compared data. The consistencies of the FY-3C data with the FY-3B data are satisfactory as they have the same specifications. Results show the consistency of the instruments. Through observations of a solar proton event and energetic electron storm, this work finds that the energetic particle data of the FY-3C satellite can accurately reflect the characteristics and intensities of space weather events. Results show the reasonable quality of the energetic particle data of the FY-3C satellite and their suitability for space weather monitoring, warning, and research.
