Vegetation Drought Response Index: 2010-Present

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.

植被干旱响应指数（Vegetation Drought Response Index，简称VegDRI）是一款干旱监测工具，由EROS的科研人员与国家干旱缓解中心、高平原区域气候中心合作开发，并获得美国农业部风险管理局的资助。VegDRI地图每两周生成一次，该类地图将基于卫星的植被状况观测数据与气候、环境数据相结合，可为美国本土提供干旱相关信息。
