Collection-2 Landsat Level-3 fractional Snow Covered Area (fSCA) Statistics Science Product

The U.S. Geological Survey (USGS) has developed and implemented an algorithm that calculates statistics from the Landsat fractional Snow Covered Area (fSCA) Science Product, which is derived from U.S. Landsat Analysis Ready Data (ARD) tiles. These tile-based fSCA statistics packages include monthly, annual, and mean annual snow cover fractions as well as monthly and annual clear pixel counts. 5-year, 10-year, and 35-year statistics are available for 12 unique time periods between 1986 and 2025. Statistics have been generated for fSCA products over the western half of the conterminous U.S. (CONUS).
