Abstract: ABSTRACT This study proposes a lunar calibration methodology to quantify the on-orbit radiometric degradation of Fengyun-4A (FY-4A) Advanced Geostationary Radiation Imager (AGRI). By analysing 408 lunar observations spanning 2017 to 2024, integrating the multi-parameter dynamic… read more here.

DOI: 10.1109/tgrs.2022.3143685
Abstract: For on-orbit radiometric calibration of infrared (IR) satellite instruments, we have developed a blackbody source whose temperature can be accurately determined by use of miniature phase change cells to provide fixed points. The temperatures and… read more here.
