Vegetation drought response index (VegDRI)

VegDRI maps are produced every two weeks and provide regional to sub-county scale information about drought's effects on vegetation. The VegDRI calculations integrate satellite-based observations of vegetation conditions, climate data, and other biophysical information such as land cover/land use type, soil characteristics, and ecological setting. The National Drought Mitigation Center produces VegDRI in collaboration with the US Geological Survey, and the High Plains Regional Climate Center, with sponsorship from the US Department of Agriculture.
