GloDET

GloDET is a free portal, hosted by DWFI, to view and download global daily evapotranspiration spatial datasets. The data is calculated by the ALEXI two-source energy balance model, developed by the U.S. Department of Agriculture’s Agricultural Research Service. Datasets may be downloaded at 375-m resolution and subsequently disaggregated to 30-m resolution. Applications of this data include estimations of the Evaporative Stress Index (ESI) and Composite Drought Index (CDI), water accounting and availability analysis in watersheds and river basins, and and field scale water productivity and crop yield estimates.
