NOAA GOES-R Series Advanced Baseline Imager (ABI) Level 2 Clear Sky Mask (ACM)

Published by NOAA National Centers for Environmental Information | National Oceanic and Atmospheric Administration, Department of Commerce | Catalog Last Checked: April 12, 2026 at 09:21 PM | Dataset Last Updated: February 16, 2018 at 12:00 AM
The Clear Sky Mask product contains an image in the form of a binary cloud mask that identifies pixels within a coverage region as clear or cloudy. The production of the clear sky mask is an important step in the processing of many other Advanced Baseline Imager (ABI) Level 2+ products that use the information generated in the production of the clear sky mask to determine the presence of a cloud. The product includes data quality information for the binary cloud mask data values for on-earth pixels. The binary cloud mask value is a dimensionless quantity. The Clear Sky Mask product image is provided at 2 km resolution on the ABI fixed grid for Full Disk, CONUS, and Mesoscale coverage regions from GOES East and West. Product data is produced for geolocated source data to local zenith angles of 90 degrees for both daytime and nighttime conditions.
