Monitoring Vegetation Drought Stress

VegDRI

The Vegetation Drought Response Index (VegDRI) is a weekly national drought tool in operation since May 2009. VegDRI maps portray vegetation conditions as plants respond to solar energy, soil moisture, and other limiting factors. The VegDRI data and models that underpin the relatively-detailed VegDRI maps indicate levels of drought stress on vegetation across the conterminous U.S. at a 1 km spatial resolution. The data are consulted each week by the U.S. Drought Monitor (USDM) map team and many other decision makers.
