Data from the first NASA satellite mission dedicated to measuring the water content of soils is now being used operationally by the U.S. Department of Agriculture (USDA) to monitor global croplands and make commodity forecasts.
The Soil Moisture Active Passive mission, or SMAP, launched in 2015 and has helped map the amount of water in soils worldwide. Now, with tools developed by a team at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, SMAP soil moisture data are being incorporated into the Crop Explorer website of the USDA’s Foreign Agricultural Service, which reports on regional droughts, floods and crop forecasts.
Crop Explorer is a clearinghouse for global agricultural growing conditions, such as soil moisture, temperature, precipitation, vegetation health and more.With global coverage every three days, SMAP can provide the Crop Explorer tool with timely updates of the soil moisture conditions that are essential for assessments and forecasts of global crop productivity.
Variations in global agricultural productivity have tremendous economic, social and humanitarian consequences. Among the users of these new SMAP data are USDA regional crop analysts who need accurate soil moisture information to better monitor and predict these variations.
This new, high-quality input from SMAP will help fill critical gaps in soil moisture information.
