On the Downscaling of Actual Evapotranspiration Maps Based on Combination of MODIS and Landsat-Based Actual Evapotranspiration Estimates [PDF]

open access: yesRemote Sensing, 2014
Downscaling is one of the important ways of utilizing the combined benefits of the high temporal resolution of Moderate Resolution Imaging Spectroradiometer (MODIS) images and fine spatial resolution of Landsat images.

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.

Actual Evapotranspiration Dominates Drought in Central Asia

open access: yesRemote Sensing, 2023
Central Asia is a drought-prone region that is sensitive to global climate change. The increased actual evapotranspiration intensifies the drought impacts in this area. However, little is known about the similarities and differences between various types

Spatial dynamics of actual daily evapotranspiration [PDF]

open access: yesGrađevinar, 2013
Estimation of actual daily evapotranspiration was conducted using SEBAL methodology, an approach based on surface energy balance equation that uses information derived from satellite image (NOAA AVHRR) and meteorological measurements from selected ...

Estimation of Potential and Actual Evapotranspiration

open access: yesHydrology Research, 1984
A model for determining the potential and actual evapotranspiration from agricultural crops is presented. The model requires only a limited number of meteorological variables, i.e. global radiation, air temperature and precipitation.

Evapotranspiration estimates for water balance scheduling in the UK [PDF]

open access: yes, 1996
This paper compares the use of different methods for estimating reference evapotranspiration (ETo) for irrigation scheduling in the UK. Methods include use of long-term averages, daily weather data and evaporimeters. The results from a single trial in

Spatial Patterns in Actual Evapotranspiration Climatologies for Europe [PDF]

open access: yesRemote Sensing, 2021
Spatial patterns in long-term average evapotranspiration (ET) represent a unique source of information for evaluating the spatial pattern performance of distributed hydrological models on a river basin to continental scale. This kind of model evaluation is getting increased attention, acknowledging the shortcomings of traditional aggregated or ...
