Misconceptions of Reference and Potential Evapotranspiration: A PRISMA-Guided Comprehensive Review

open access: yesHydrology, 2022
One of the most important parts of the hydrological cycle is evapotranspiration (ET). Accurate estimates of ET in irrigated regions are critical to the planning, control, and regulation of agricultural natural resources.

Determinants of the ratio of actual to potential evapotranspiration [PDF]

open access: yesGlobal Change Biology, 2019
AbstractA 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). Ω represents the water availability and is fundamentally linked to canopy–atmosphere coupling.

Deriving potential evapotranspiration from satellite-based reference evapotranspiration, Upper Tekeze Basin, Northern Ethiopia

open access: yesJournal of Hydrology: Regional Studies, 2022
Study region: Zamra catchment, Upper Tekeze Basin, Northern Ethiopia. Study focus: Direct field estimates of potential evapotranspiration (PET) remain a challenge, because they are expensive and have limited spatial representativeness.

Modeling potential evapotranspiration based on energy balance

open access: yesShui kexue jinzhan, 2022
To investigate a more accurate method for potential evapotranspiration estimation under climate change, three sets of experiments were conducted using small lysimeters at Wudaogou experimental station on the Huaibei Plain (China), and a new model of ...

A MODEL FOR ESTIMATING ACTUAL EVAPOTRANSPIRATION FROM POTENTIAL EVAPOTRANSPIRATION [PDF]

open access: yesHydrology Research, 1975
A model for calculating the daily actual evapotranspiration based on the potential one is presented. The potential evapotranspiration is reduced according to vegetation density, water content in the root zone, and the rainfall distribution. The model is tested by comparing measured (EAm) and calculated (EAc) evapotranspirations from barley, fodder ...

Spatiotemporal Changes of sc-PDSI and Its Dynamic Drivers in Yellow River Basin

open access: yesAtmosphere, 2022
Droughts in the Yellow River Basin (YRB), a typical large river in arid to semiarid regions, have been studied extensively. However, the details of the dynamic drivers of meteorological droughts, such as precipitation (P), reference evapotranspiration ...

Understanding the daily cycle of evapotranspiration: a method to quantify the influence of forcings and feedbacks [PDF]

open access: yes, 2010
A method to analyze the daily cycle of evapotranspiration over land is presented. It quantifies the influence of external forcings, such as radiation and advection, and of internal feedbacks induced by boundary layer, surface layer, and land surface ...
