    • Estimates of Road Salt Application across the Conterminous United States, 1992-2019 (ver. 2.0, August 2023)

    Metadata Updated: September 24, 2025

    Annual estimates of road salt application were initially developed for the conterminous United States for the calendar years 1992 through 2015. As more data became available, years 2016 through 2019 were added to the dataset. The final dataset consists of 28 rasters in Geostationary Earth Orbit Tagged Image File Format (GeoTIFF), one for each year from 1992 through 2019. The final estimates (in pounds) were derived from several data sources, which include road density and proportion of developed land use, depth and spatial extent of long-term snowfall, and the production and distribution of salt sources by state. The extent is the conterminous United States, and the spatial resolution is one-square kilometer.
