Abstract

The JPSS-1 Visible/Infrared Imaging Radiometer Suite (VIIRS) is a key sensor on the NOAA-20 satellite launched on November 18, 2017 into a polar orbit of 824 km nominal altitude. The NOAA-20 satellite is a weather and climatemonitoring mission for the Joint Polar Satellite System (JPSS) partnership comprised of NASA and NOAA. VIIRS collects radiometric and imagery data of the Earth’s atmosphere, oceans, and land surfaces in 22 spectral bands spanning the visible and infrared spectrum from 0.4 to 12.5 micron. This paper summarizes the radiometric response trending for the 7 VIIRS thermal emissive bands (3.7 to 12.5 μm), covering both pre-launch thermal-vacuum testing and early onorbit checkout period, including the discovery, investigation and resolution of a response degradation anomaly for several long-wave infrared (LWIR) bands. Multiple corrections for response sensitivities based on pre-launch characterizations are applied to significantly improve the precision of the trended response to accurately assess the health of the emissive band radiometric response stability and quickly assess the impact of various experiments on the observed LWIR degradation.
