The fractional snow cover algorithm uses GOES-R ABI spectral information in the visible and near-visible portion of the energy spectrum to retrieve sub-pixel fractional snow cover and grain size estimates via computationally efficient spectral mixture modeling. This product supports a number of operational applications that include: assimilation into NOAA’s NOHRC snow model, as well as hydrologic forecasts and warnings, including river and flood forecasts, water management, snowpack monitoring and analysis, and climate studies.
