Spatial-Temporal Variation in Paddy Evapotranspiration in Subtropical Climate Regions Based on the SEBAL Model: A Case Study of the Ganfu Plain Irrigation System, Southern China

Remote Sensing, 2022
The surface energy balance algorithm for land (SEBAL) is a commonly used method for estimating evapotranspiration (ET) at a regional scale; however, the cloudy and rainy characteristics of subtropical monsoon regions pose a greater challenge for ...

Estimation of actual evapotranspiration using SEBAL and METRIC algorithms and validation with lysimetric data in arid regions

Desert, 2022
Estimation of actual evapotranspiration (ET) in large areas is an important part of water resources management. In recent years, remote sensing has been successfully used in ET estimation, which is supposed to be more accurate for estimating ET on regional and agricultural scales.

Global Performance of Remote Sensing‐Based and Reanalysis‐Driven Models to Estimate Open Water Evaporation

Water Resources Research, Volume 62, Issue 7, July 2026.
Abstract Evaporation plays an essential role in the water cycle, influencing local and regional climates while directly impacting water availability in lakes. However, directly measuring evaporation over water bodies remains challenging due to the high costs of installing and maintaining the required in situ instrumentation.

A closed‐form equation linking soil moisture and evaporation

Vadose Zone Journal, Volume 25, Issue 3, May/June 2026.
Abstract Estimating evaporation from surface soil moisture data poses a persistent challenge for modeling the hydrological cycle. Deriving a physics‐based solution to convert single‐probe soil moisture data into evaporation estimates has always been challenging. Such an equation would enhance hydrological models and remote sensing methods.

Development and Evaluation of a Simple Geometric Radiation Absorption Model for Discontinuous Canopies With Ellipsoidal Crown Shapes

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 5, May 2026.
Abstract Large‐scale canopy models utilizing satellite data typically rely on simplified models to describe radiation absorption by vegetation. However, these models' accuracy can be limited when applied to heterogeneous row‐oriented canopies because of assumptions of canopy homogeneity, or oversimplification of the impacts of heterogeneity. This study

The Importance of Spatial Variability in Estimating Evapotranspiration From a Subalpine Wetland

Hydrological Processes, Volume 40, Issue 3, March 2026.
Spatial trends in evapotranspiration were quantified in a sub‐alpine wetland, with higher rates occurring in the wetlands' western portion. This spatial variability suggests care must be taken when estimating evapotranspiration via point measurements. The METRIC approach to modelling evapotranspiration performed reasonably well and should be explored ...

Variation in Water‐Use Strategies of Prosopis velutina in Southern Arizona

Ecohydrology, Volume 19, Issue 1, January‐February 2026.
ABSTRACT In semi‐arid regions of the United States, mesquite trees are widely distributed across the landscape and play a pivotal ecological role, influencing hydrological processes and contributing to biodiversity. This is especially true in riparian areas, where understanding the adaptive water‐use strategies of facultative phreatophytes is essential
