A evapotranspiração e interceptação reais (ETIa) (decadal, em mm/dia) é a soma da evaporação do solo (E), da transpiração da copa (T) e da evaporação da chuva interceptada pelas folhas (I). O valor de cada pixel representa a média diária de ETIa em uma determinada década.

Termos de Uso
A Organização das Nações Unidas para Alimentação e Agricultura (FAO) tem o mandato de coletar, analisar, interpretar e divulgar informações relacionadas à nutrição, alimentos e agricultura. Nesse sentido, ela publica vários bancos de dados sobre temas relacionados ao mandato da FAO e incentiva o uso deles para fins científicos e de pesquisa. De acordo com os princípios de abertura e compartilhamento previstos na Licença de dados abertos para bancos de dados estatísticos e com o mandato da FAO, os dados do Portal de acesso aberto à produtividade da água (WaPOR), como parte do AQUASTAT, o Sistema Global de Informações sobre Água e Agricultura da FAO, estão disponíveis sem custo financeiro para a comunidade de usuários.
