Abstract

The Day Night Band (DNB), mounted on the Visible Infrared Imaging Radiometer Suite (VIIRS) on board the Suomi National Polar-orbiting Partnership (NPP), has the unique ability to image cloud and surface features with reflected moonlight and nonlunar nighttime illumination sources. However, the radiometric calibration is too difficult to be calculated directly at night due to extremely low radiance. The Dome C in Antarctic and Railroad Valley Playa in Nevada are utilized to calibrate the DNB High Gain Stage (HGS) at night due to their invariable surface properties. The mean value of the relative errors based on Dome C site is -7.41% and RVP is -4.14%. The results suggest that there is an average bias in the DNB HGS on-orbit calibration and an unobvious trend exists due to the changing relative spectral responses over time.
