Reference crop evapotranspiration or reference evapotranspiration, denoted as ETo or ETref, is the estimation of the evapotranspiration from the "reference surface. "The reference surface is a hypothetical grass reference crop with an assumed crop height of 0. 12 m, a fixed surface resistance of 70 s/m and an albedo of 0. 23. The reference surface closely resembles an extensive surface of green, well-watered grass of uniform height, actively growing and completely shading the ground. The fixed surface resistance of 70 s/m implies a moderately dry soil surface resulting from about a weekly irrigation frequency. 1, record 1, English, - reference%20evapotranspiration

La evapotranspiración de referencia (ETo) es un parámetro agro-meteorológico de gran importancia para muchas áreas de estudio como la geotecnia, climatología e hidrología, donde su mayor importancia recae en el cálculo de la evapotranspiración de cultivo (ETc). 1, record 1, Spanish, - evapotranspiraci%C3%B3n%20de%20referencia
