NationalSoilMoisture.com provides high-resolution gridded soil moisture products derived from in situ soil moisture measurements, Natural Resources Conservation Service SSURGO soil characteristics, and PRISM data. The project combines data from multiple federal and regional agencies to create comprehensive data products for the United States including Alaska, Hawaii, and Puerto Rico. These products include near real-time soil moisture percentiles derived from in situ data, modeled NLDAS data, and the NASA’s Soil Moisture Active Passive (SMAP) satellite as well as a near real-time blended product.
This project is a joint effort between the United States Geological Survey’s (USGS) Center for Integrated Data Analytics, several branches of the United States Department of Agriculture (USDA), National Oceanic and Atmospheric Administration (NOAA), the U.S. Climate Reference Network (CRN), and NIDIS.
