Rzeczywiste parowanie i intercepcja (ETIa) (dekadowe, w mm/dzień) to suma parowania z gleby (E), transpiracji z korony drzew (T) i parowania z opadów deszczu przechwyconych przez liście (I). Wartość każdego piksela
reprezentuje średnią dzienną wartość ETIa w danym dekalce.

Organizacja Narodów Zjednoczonych do spraw Wyżywienia i Rolnictwa (FAO) ma za zadanie zbierać, analizować, interpretować i rozpowszechniać informacje związane z odżywianiem, żywnością i rolnictwem. W tym celu publikuje szereg baz danych dotyczących tematów związanych z mandatem FAO i zachęca do ich wykorzystywania w celach naukowych i badawczych. Zgodnie z zasadami otwartości i udostępniania, które są podstawą licencji na otwarte dane w przypadku statystycznych baz danych, oraz zgodnie z mandatem FAO dane z portalu Water Productivity Open Access Portal (WaPOR), który jest częścią AQUASTAT – globalnego systemu informacji FAO o wodzie i rolnictwie, są dostępne bezpłatnie dla społeczności użytkowników.
