Reference evapotranspiration (RET) is defined as the evapotranspiration from a
hypothetical reference crop and it simulates the behaviour of a well-watered
grass surface. The value of each pixel represents the average of the daily
reference evapotranspiration for that specific 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.
