Climate Hazards Center Data Archive

Using a combination of remote sensing data and ground observations as inputs, CHC scientists have developed rainfall estimation techniques and other resources to support drought monitoring and predict crop performance in parts of the world vulnerable to crop failure. Policymakers within governments and non-governmental organizations rely on CHC decision-support products to make critical resource allocation decisions. The CHC's scientific focus is "geospatial hydroclimatology," with an emphasis on the early detection and forecasting of hydroclimatic hazards related to food-security droughts and floods. Basic research seeks an improved understanding of the climatic processes that govern drought and flood hazards in FEWS NET countries (https://fews.net/). The CHC develops better techniques, algorithms, and modeling applications in order to use remote sensing and other geospatial data for hazards early warning.

借助遥感数据与地面观测数据的融合，CHC科研人员已研发出降雨估算技术及其他资源，旨在支撑干旱监测并预测全球易受作物歉收影响区域的作物表现。各国政府与非政府组织的政策制定者，均依赖于CHC的决策支持产品以作出关键的资源配置决策。CHC的科研焦点集中于“地理空间水文学”，特别强调对与粮食安全相关的干旱与洪水等水文学危害的早期检测与预测。基础研究致力于加深对FEWS NET国家（https://fews.net/）干旱与洪水危害所受控的气候过程的理解。CHC致力于开发更优的技术、算法以及模型应用，以便利用遥感及其他地理空间数据进行灾害的早期预警。
