VegDRI maps are produced every two weeks and provide regional to sub-county scale information about drought's effects on vegetation. Click on “Change Maps” tab for comparisons to the previous map, a month previous and a year ago. Clicking on the “Time Series” tab brings up an animation of changes to the map in a given year.
The Evaporative Stress Index (ESI) describes temporal anomalies in evapotranspiration (ET), highlighting areas with anomalously high or low rates of water use across the land surface. The ESI also demonstrates capability for capturing early signals of “flash drought”, brought on by extended periods of hot, dry and windy conditions leading to rapid soil moisture depletion.
