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.

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 ...

ECOSTRESS and CIMIS: A Comparison of Potential and Reference Evapotranspiration in Riverside County, California

open access: yesRemote Sensing, 2020
The ECOsystem Spaceborne Thermal Radiometer Experiment on Space Station (ECOSTRESS) provides remotely-sensed estimates of evapotranspiration at 70 m spatial resolution every 1–5 days, sampling across the diurnal cycle.

Effect of projected climate change on potential evapotranspiration in the semiarid region of central India

open access: yesJournal of Water and Climate Change, 2021
The performance of potential evapotranspiration (PET) methods such as pan evaporation (physical measurement), empirical formulas (Penman–Monteith (PM), Hargreaves and Thornthwaite) and satellite-derived PET (MOD16) were assessed in a semiarid region of ...

potential evapotranspiration

open access: yes, 2014
Contained within the 4th Edition (1974) of the Atlas of Canada is a set of three maps relating the effects and dependency of vegetation on environmental variables. One map shows the average annual potential evapotranspiration in inches from ground and plant surfaces for areas where there is a continuous vegetation cover and sufficient soil moisture for

Analysis of the Accuracy Comparison of Five Different Models of Valiantzas Equation in the Estimation of Reference Evapotranspiration [PDF]

open access: yesعلوم و مهندسی آبیاری, 2018
Evapotranspiration is one of the most important factors in hydrological cycle. Potential evapotranspiration is used to design in irrigation and drainage networks and hydrological studies (Davis & Dukes, 2010).
