L2 Cloud Mask (CLDMSK_L2) Product Description

The L2 Continuity Cloud Mask product is a Level-2 product generated at 750-m and 1000-m (at nadir) spatial resolutions. The algorithm employs a series of visible and infrared threshold and consistency tests to specify confidence that an unobstructed view of the Earth's surface is observed. . A 1-pixel wide cloud adjacency flag is also provided. Radiometrically accurate radiances are required, so holes in the Cloud Mask will appear wherever the input radiances are incomplete or of poor quality. The L2 Continuity Cloud Mask data product file always has a prefix of CLDMSK_L2 and contains data collected from one of two platforms: SNPP/VIIRS or Aqua/MODIS.
