Il componente dati sull'evaporazione (E) (decadale, in mm/giorno) è l'evaporazione
effettiva della superficie del suolo. Il valore di ogni pixel rappresenta l'evaporazione
reale media giornaliera per quella specifica decade.

L'Organizzazione delle Nazioni Unite per l'alimentazione e l'agricoltura (FAO) ha il mandato di raccogliere, analizzare, interpretare e diffondere informazioni relative a nutrizione, alimenti e agricoltura. A questo proposito, pubblica una serie di database su argomenti correlati al mandato della FAO e ne incoraggia l'utilizzo per scopi scientifici e di ricerca. In linea con i principi
di apertura e condivisione previsti dalla licenza per dati aperti per
database statistici e
in linea con il mandato della FAO, i dati del Water Productivity Open
Access Portal (WaPOR), nell'ambito
di AQUASTAT, il sistema
informativo globale della FAO su acqua e agricoltura, sono disponibili senza costi per la community di utenti.
