Climate change is expected to alter precipitation patterns worldwide, potentially increasing chances for drought in places where rainfall decreases over extended periods. Currently, droughts are responsible for $6 to $8 billion in losses each year in the United States alone. Accurate monitoring of drought conditions is vital in helping to mitigate drought impacts, both now and in the future.

VegDRI, short for Vegetation Drought Response Index, is a drought-monitoring tool developed by scientists at EROS in collaboration with the National Drought Mitigation Center and the High Plains Regional Climate Center, with sponsorship from the U.S. Department of Agriculture's Risk Management Agency. VegDRI maps, produced every two weeks, combine satellite-based observations of vegetation conditions with climate and environmental data to provide drought information for the conterminous United States.
