The National Operational Hydrologic Remote Sensing Center (NOHRSC), a division of the National Oceanic and Atmospheric Administration (NOAA), 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 National Weather Service (NWS), other government agencies, the private sector, and the public to support operational and research hydrology programs across the nation.
