Die tatsächliche Evapotranspiration und Interzeption (ETIa) (dekadal, in mm/Tag) ist die Summe aus Bodenverdunstung (E), Transpiration der Baumkrone (T) und Verdunstung von Regenwasser, das von Blättern abgefangen wird (I). Der Wert jedes Pixels entspricht dem durchschnittlichen täglichen ETIa in einer bestimmten Dekade.

Die Ernährungs- und Landwirtschaftsorganisation der Vereinten Nationen (FAO) ist beauftragt, Informationen zu Ernährung, Lebensmitteln und Landwirtschaft zu sammeln, zu analysieren, zu interpretieren und zu verbreiten. In diesem Zusammenhang veröffentlicht sie eine Reihe von Datenbanken zu Themen, die mit dem Mandat der FAO zusammenhängen, und ermutigt zur Nutzung dieser Datenbanken für wissenschaftliche und Forschungszwecke. Entsprechend den Grundsätzen der Offenheit und des Teilens, die in der Open Data Licensing For Statistical Databases (Offene Datenlizenzierung für statistische Datenbanken) vorgesehen sind, und entsprechend dem Mandat der FAO sind Daten aus dem Water Productivity Open Access Portal (WaPOR) (Offenes Zugangsportal für Wasserproduktivität) als Teil von AQUASTAT – dem globalen Informationssystem der FAO für Wasser und Landwirtschaft – für die Nutzergemeinschaft kostenlos verfügbar.
