Development of Prototype National Water Model Soil Moisture Products for Drought Monitoring

NIDIS Supported Research
NIDIS-Supported Research
Main Summary

The National Water Model offers many variables relevant to drought monitoring, including soil moisture at several depths and streamflow, and it does so on an unprecedentedly high-resolution grid of 250 m to 1 km. Streamflow is an indicator of hydrological drought, with low flows indicating potential fresh-water shortages. This project uses NIDIS-funded, in-ground soil moisture measurements to evaluate the National Water Model’s soil moisture data and, with regular input from stakeholders at the National Drought Mitigation Center (operators of the U.S. Drought Monitor), is developing new methods to visualize soil moisture and streamflow anomalies that will provide new insight for Drought Monitor authors.
