Abstract

The Earth-observing Visible Infrared Imaging Radiometer Suite (VIIRS) has 14 reflective solar bands (RSBs), covering wavelengths from 412 to 2250 nm. The first VIIRS instrument is aboard the Suomi National Polar-orbiting Partnership (SNPP) satellite launched on October 28, 2011. The RSBs use a sunlit onboard solar diffuser (SD) to calibrate, with the dark count obtained through viewing the Space View (SV) port. Stray light contaminations in the SV and/or the SD View, if present, could negatively impact on the radiometric calibration accuracy. Here, we assess the stray light contamination in the SNPP VIIRS Space View, focusing on band M1 (412 nm).
