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 ...

Determinants of the ratio of actual to potential evapotranspiration

Global Change Biology, 2019
A widely used approach for estimating actual evapotranspiration (AET) in hydrological and earth system models is to constrain potential evapotranspiration (PET) with a single empirical stress factor (Ω = AET/PET).

Irrigation‐Induced Potential Evapotranspiration Decrease in the Heihe River Basin, Northwest China, as Simulated by the WRF Model

Journal of Geophysical Research: Atmospheres, 2020
Evapotranspiration occurs via land‐atmosphere coupling. To understand the impacts of irrigation on local potential evapotranspiration, we carried out a couple of simulations with the Weather Research and Forecast (WRF) model, where an irrigation scheme ...

Evapotranspiration Potential of Green Infrastructure Vegetation

2021
To better understand the evapotranspiration potential of urban vegetation, daily evapotranspiration (ET) of four species commonly found in green infrastructure in New York City and Philadelphia (A. incaranta, L. muscari, C. lurida, and E. purpurea) was measured using microlysimeters.

Scaling Potential Evapotranspiration with Greenhouse Warming

Journal of Climate, 2014
Abstract Potential evapotranspiration (PET) is a supply-independent measure of the evaporative demand of a terrestrial climate—of basic importance in climatology, hydrology, and agriculture. Future increases in PET from greenhouse warming are often cited as key drivers of global trends toward drought and aridity.

Potential Evapotranspiration in Arid Regions

Journal of Applied Meteorology, 1964
Abstract The concept of potential evapotranspiration, as applied to arid regions, is examined using an energy balance approach suggested by Budyko. Using data for Yuma, Ariz., it is shown that a 50 per cent increase in the relative humidity of the air above an irrigated field is accompanied by a 10 to 15 per cent decrease in potential ...

A Simple Apparatus for Measuring Potential Evapotranspiration

Nature, 1952
THE combined process of evaporation from the soil and transpiration from plants is known as ‘evapotranspiration’. The amount of moisture so used varies from place to place and depends mainly on climate (especially temperature and precipitation) and the closeness of the vegetative cover.

Potential evapotranspiration at Simcoe, Southern Ontario

Archiv für Meteorologie, Geophysik und Bioklimatologie Serie B, 1968
Several approaches to the evaluation of potential evapotranspiration (PE) are discussed from the point of view of the energy balance equation. Hourly and daily PE were evaluated for an irrigated ryegrass site near Simcoe in Southern Ontario during the summer of 1967 using the Bowen ratio and Penman solution of the energy balance equation, Thornthwaite ...

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.
