VIIRS/NOAA-20 Dark Target Aerosol L2 6-Min Swath (v2.0) provides global satellite-derived measurements of Aerosol Optical Thickness (AOT) and related properties over land and ocean every 6 minutes. The dataset is produced by NASA using the Visible Infrared Imaging Radiometer Suite (VIIRS) on the NOAA-20 satellite, applying a dark target algorithm with heritage from MODIS instruments on Terra and Aqua. This Version-2 collection represents the first Level-2 Dark Target Aerosol product derived specifically from the NOAA-20 VIIRS source.
