U.S. Topsoil Moisture Monitoring

Associated Agencies

NOAA National Weather Service (NWS) Climate Prediction Center (CPC)

The Climate Prediction Center produces Topsoil Moisture Monitoring maps based on United States Department of Agriculture (USDA) state reports of topsoil moisture conditions.

Means are calculated from historical weekly data published by the U.S. Department of Agriculture's (USDA's) National Agricultural Statistics Service using the closest date to the equivalent date for the year. Results are based on the short and very short percentages of topsoil moisture (upper 6 inches) reported by the USDA. Reports are based on subjective observations.
