Complexity and Predictability of Daily Actual Evapotranspiration Across Climate Regimes

Water Resources Research, 2023
Estimation of actual evapotranspiration (ETa) is challenging due to its complex interactions with surrounding environments; thus, understanding the complexity and predictability of ETa along with its influencing factors is essential to improve ETa ...

Long‐term mean changes in actual evapotranspiration over China under climate warming and the attribution analysis within the Budyko framework

International Journal of Climatology, 2021
In this study, the temporal variation of actual evapotranspiration (AE) over China during 1980–2015 is analysed based on an ensemble of six reanalyses and a complementary‐relationship‐based AE dataset.

Actual evapotranspiration by use of MODIS data

2012 IEEE International Geoscience and Remote Sensing Symposium, 2012
The aim of this research is to assess a technique to retrieve actual evapotranspiration (ET) maps from remote sensing images by the combination of two different procedures. The first one, known as triangle method, computes the evapotranspiration fraction (EF) defined as the ratio LE/Rn, where Rn is the net radiation at the surface and LE is the latent ...

Alternate corrections for estimating actual wetland evapotranspiration from potential evapotranspiration

Wetlands, 2006
Corrections can be used to estimate actual wetland evapotranspiration (AET) from potential evapotranspiration (PET) as a means to define the hydrology of wetland areas. Many alternate parameterizations for correction coefficients for three PET equations are presented, covering a wide range of possible data-availability scenarios.

Practical prediction of actual evapotranspiration

Irrigation Science, 1980
A simplified method of estimating actual evapotranspiration of crops during an irrigation interval in which soil-moisture deficits occur is presented. With some simplifying assumptions, a relation is developed between a crop-dependent critical leaf water potential, potential evapotranspiration rates, and the fraction of available soil-moisture at which

Evaluation of actual evapotranspiration measured by large‐scale weighing lysimeters in a humid alpine meadow, northeastern Qinghai‐Tibetan Plateau

Hydrological Processes, 2021
The accurate estimation of evapotranspiration (ET) is essential for assessing water availability and requirements of regional‐scale terrestrial ecosystems, and for understanding the hydrological cycle in alpine ecosystems.

Estimating actual evapotranspiration using RS and GIS

SPIE Proceedings, 2006
Evapotranspiration, a major component in terrestrial water balance and net primary productivity models, is difficult to measure and predict. Remote sensing cannot provide a direct measurement of evapotranspiration (ET) but it can provide a reasonably good estimate of Evaporative Fraction (EF), defined as the ratio of ET and available energy.

Pan Evaporation, Potential and Actual Evapotranspiration

Journal of Applied Meteorology, 1967
Abstract A formula for estimating the evapotranspiration rate from temperature and relative humidity data is given. Results of some tests of the accuracy of the equation indicate that it is better than other equations based on a similar number of variables.
