NOHRSC National Snow Analyses
NOAA / National Weather Service / National Operational Hydrologic Remote Sensing Center (NOHRSC)
The National Operational Hydrologic Remote Sensing Center (NOHRSC) provides remotely-sensed and modeled hydrology products for the coterminous U.S. and Alaska for the protection of life and property and the enhancement of the national economy.
NOHRSC airborne, satellite, and modeled snow data and products are used by the National Weather Service, other government agencies, the private sector, and the public to support operational and research hydrology programs across the nation. The NOHRSC produces snow products and information that include estimates of snow water equivalent, snow depth, snow pack temperatures, snow sublimation, snow evaporation, estimates of blowing snow, modeled and observed snow information, airborne snow data, satellite snow cover, historic snow data, and time-series for selected modeled snow products.
