Similarity and difference of potential evapotranspiration and reference crop evapotranspiration – a review

Agricultural Water Management, 2020
Abstract Potential evapotranspiration (ETp) and reference crop evapotranspiration (ETo) differ in their developments, concepts, equations and application fields, however, many researchers have mixed the utilization of the two terms. Thus, it is necessary to clarify the terms to guide their proper usage.

Evaluation of six potential evapotranspiration models for estimating crop potential and actual evapotranspiration in arid regions

Journal of Hydrology, 2016
Abstract Using potential evapotranspiration (PET) to estimate crop actual evapotranspiration (AET) is a critical approach in hydrological models. However, which PET model performs best and can be used to predict crop AET over the entire growth season in arid regions still remains unclear. The six frequently-used PET models, i.e.

Estimating Potential Evapotranspiration

Journal of the Irrigation and Drainage Division, 1982
Increasing population and needs for an augmented food supply give greater importance to improved procedures for estimating agricultural water requirements both for irrigation and for rain-fed agriculture. Four methods for estimating potential evapotranspiration are compared and evaluated.

Potential evapotranspiration and continental drying

Nature Climate Change, 2016
Tendencies towards climate-change-induced continental drying, as characterized by offline-computed runoff and other potential-evapotranspiration-dependent metrics, may be artefactual. Consequently they may be much weaker and less extensive than previously thought.

AN EXPERIMENT TO MEASURE POTENTIAL EVAPOTRANSPIRATION

Canadian Journal of Research, 1948
A method of obtaining daily values of the potential evaporating power of the atmosphere was used for the first time in Canada in 1947. The results verify Thornthwaite's formula for computing potential evapotranspiration in southern Ontario. The correlation between average runoff and computed water surplus for several watersheds in Ontario and Quebec ...
