Modelling High-Resolution Actual Evapotranspiration through Sentinel-2 and Sentinel-3 Data Fusion

open access: yesRemote Sensing, 2020
The Sentinel-2 and Sentinel-3 satellite constellation contains most of the spatial, temporal and spectral characteristics required for accurate, field-scale actual evapotranspiration (ET) estimation. The one remaining major challenge is the spatial scale

Spatiotemporal Distribution Characteristics of Actual Evapotranspiration in the Qinghai–Tibet Plateau

open access: yesAtmosphere, 2023
Evapotranspiration is a key part of the water cycle between the atmosphere and the land surface, and it is an important parameter for studying the land–atmosphere system. Change and evolution have important implications.

Assessment of evapotranspiration simulations in the Malše basin

open access: yesSoil and Water Research, 2009
The application of the distributed hydrological model brings the benefits of assessment of the spatially distributed quantities which are hard to measure in the field over a larger area, e.g. evapotranspiration.

Long term variations of actual evapotranspiration over the Tibetan Plateau

open access: yes, 2021
. Terrestrial actual evapotranspiration (ETa) is a key parameter controlling the land-atmosphere interaction processes and the water cycle. However, the spatial distribution and temporal changes of ETa over the Tibetan Plateau (TP) remain very uncertain.

Evaluation of Penman-Monteith Model Based on Sentinel-2 Data for the Estimation of Actual Evapotranspiration in Vineyards

open access: yesRemote Sensing, 2021
Water scarcity is one of the most important problems of agroecosystems in Mediterranean and semiarid areas, especially for species such as vineyards that largely depend on irrigation.

Yield, Evapotranspiration, Production Functions, Crop Coefficients, Water Productivity and Soil‐Water Extraction of Three Watermelon Varieties

open access: yesIrrigation and Drainage, EarlyView.
ABSTRACT While watermelon is an important commodity in the United States and worldwide, some of the fundamental watermelon productivity indices (crop evapotranspiration [ETc], transpiration [Tr], evaporation [E], ET‐yield production functions [ETYPF], basal crop coefficients [Kcb], crop water productivity [CWP], soil‐water extraction [SWE]) have not ...

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.
