Description
The actual evapotranspiration and interception (ETIa) (dekadal, in mm/day) is the sum of the soil evaporation (E), canopy transpiration (T), and evaporation from rainfall intercepted by leaves (I). The value of each pixel represents the average daily ETIa in a given dekad.

Terms of Use
The Food and Agriculture Organization of the United Nations (FAO) is mandated to collect, analyze, interpret, and disseminate information related to nutrition, food, and agriculture. In this regard, it publishes a number of databases on topics related to FAO's mandate, and encourages the use of them for scientific and research purposes. Consistent with the principles of openness and sharing envisioned under the Open Data Licensing For Statistical Databases, and consistent with the mandate of FAO, data from the Water Productivity Open Access Portal (WaPOR), as part of AQUASTAT - FAO's Global Information System on Water and Agriculture, is available free to the user community.
