摘要：

The VIIRS instrument on Suomi-NPP performs its primary radiometric calibration using the Solar Diffuser, which degrades with exposure to UV light. The Solar Diffuser is monitored by the Solar Diffuser Stability Monitor. In this paper, we evaluate potential improvements to the algorithms that generate the resulting H-factors, including updates to the screen transmission functions and new methodologies to increase the amount of useful data. We also track the on-orbit degradation of the SDSM detectors and predict the long-term performance of the sensors.
