Evapotranspiration: Potential or Reference?

open access: yesEDIS, 2003
The objective of this article is to define two commonly used evapotranspiration (ET) concepts: potential evapotranspiration (ETp) and reference evapotranspiration (ETo); and to provide insight on the differences between the two terms.

Reference evapotranspiration estimation inside greenhouses

open access: yesScientia Agricola, 2003
Because of the large area occupied by a class A pan, alternative methods have been sought to estimate reference evapotranspiration (Eto) inside greenhouses. The objective of this work was to compare ETo estimated by different methods inside and outside a

Effects on Net Irrigation Water Requirement of Joint Distribution of Precipitation and Reference Evapotranspiration

open access: yesAgriculture, 2022
To establish the uncertain influence that the joint distribution of precipitation and reference evapotranspiration has on net irrigation water requirement, a Copula function–Monte Carlo method (CFMC) was proposed to calculate the probability of ...

Estimation of Actual Evapotranspiration in Panam Canal Command Using Remote Sensing and Geographical Information System (GIS)

open access: yesInternational Journal of Environment and Geoinformatics, 2021
Estimation of reference evapotranspiration (ET0 ) and actual evapotranspiration (ETc ) is a key factor for estimation of crop water requirement, water balance and irrigation scheduling. The FAO-56 Penman–Monteith equation has been accepted universally

Comparison of the Concepts of Potential and Reference Evapotranspiration using Lysimetric Data in Qazvin Province [PDF]

open access: yesمحیط زیست و مهندسی آب, 2021
In order to determine the amount of irrigation water, it is required to calculate the amount of the plant water requirement or evapotranspiration. The equations used to calculate evapotranspiration do not use the same climatic parameters and are not ...
