NOAA GOES-R Series Advanced Baseline Imager (ABI) Level 2 Snow Cover

ABI-L2-FSC

browse graphicExample of the Snow Cover product (right figure) as generated by the GOES-R Snow Cover algorithm
The GOES-R ABI Snow Cover product contains an image with pixel values identifying the fraction of their areas covered by snow. The product includes data quality information that provides an assessment of the snow cover data values for on-earth pixels. The units of measure for the snow cover value is percent. The Snow Cover product image is produced on the ABI fixed grid at 2 km resolution for Full Disk, CONUS and Mesoscale coverage regions. Product data is produced under the following conditions: Existence of land; Clear sky; Geolocated source data to local zenith angles of 90 degrees and solar zenith angles of 90 degrees.

Processing Steps
  • The Snow Cover product is generated by the GOES-R ABI Snow Cover ground processing algorithm. The algorithm relies on atmospherically-corrected surface reflectances derived as part of the determination of the surface albedo and does not use ABI Level 1b data inputs directly. The product is generated using spectral mixture analysis with a look-up table containing spectral reflectances of individual surfaces calculated from a radiative transfer model, and also a physical retrieval utilizing a spectral library lookup table to account for the dependency of reflectance on snow grain size, and local and solar zenith angles. The algorithm maintains an endmember memory file that contains two values per pixel indicating the endmember identifiers of the last modeled endmembers. Types of endmembers are land surface materials such as snow, vegetation, and rock, and are characterized using unique reflectance spectra based on modeled and field measurements. The endmemory memory file is re-initialized daily.
  • The GOES-16 ABI Snow Cover algorithm reached beta maturity.
  • The GOES-16 ABI Snow Cover algorithm reached provisional maturity.
  • The GOES-16 ABI Snow Cover algorithm reached full validation maturity.
