AI-generated Key Takeaways
-
The FAO WaPOR dataset provides dekadal (10-day) estimates of actual evapotranspiration and interception (ETIa) in mm/day.
-
ETIa values represent the combined daily average of soil evaporation, plant transpiration, and interception evaporation by leaves.
-
Data is freely available for research and scientific purposes, covering the period from 2009-01-01 to 2023-03-01.
-
Spatial resolution of the dataset is 248.2 meters.

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.

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.
