Paper Abstract

The VIIRS radiometric calibration approach relies on views of space above the earth limb to estimate a “zero offset” which is subtracted from the other instrument views (earth, solar diffuser, on board black body). This zero offset estimation is compromised when the Moon lies within the space view. The current calibration approach has a conservative method to determine when the space view is contaminated or potentially contaminated by the Moon. We outline a new approach to detecting lunar contamination, and for estimating the zero offset for contaminated scans. Our approach offers the potential to greatly reduce the number of scans classified as lunar contaminated and thus of lower quality due to the alternate calibration process used in the current operational approach. Thus, such an alternative approach could increase the number of nominal, high quality VIIRS scans available for science analyses.
