Remotely sensed terrestrial open water evaporation [PDF]

Scientific Reports, 2023
Terrestrial open water evaporation is difficult to measure both in situ and remotely yet is critical for understanding changes in reservoirs, lakes, and inland seas from human management and climatically altered hydrological cycling.

Post-processed data and graphical tools for a CONUS-wide eddy flux evapotranspiration dataset [PDF]

Data in Brief, 2023
Large sample datasets of in situ evapotranspiration (ET) measurements with well documented data provenance and quality assurance are critical for water management and many fields of earth science research.

Performance Mapping and Weighting for the Evapotranspiration Models of the OpenET Ensemble

Water Resources Research
Evapotranspiration (ET) accounts for the majority of water available from precipitation in the terrestrial water cycle, and improvements to the accuracy, resolution, and coverage of ET data can enhance hydrologic models and assessments.

Assessing Satellite-Derived OpenET Platform Evapotranspiration of Mature Pecan Orchard in the Mesilla Valley, New Mexico

Remote Sensing
Pecan is a major crop in the Mesilla Valley, New Mexico. Due to prolonged droughts, growers face challenges related to water shortages. Therefore, irrigation management is crucial for farmers.

Intercomparison of citrus evapotranspiration among eddy covariance, OpenET ensemble models, and the Water and Energy Balance Model (BAITSSS)

Agricultural Water Management
Remote sensing-based surface energy balance algorithms have been used to estimate water use of various crops. However, citrus evapotranspiration (ET) estimation is challenging mainly due to evergreen leaves and a clumped canopy structure.

Evaluation and comparison of OpenET models for estimating soil water depletion of irrigated alfalfa in Arizona

Agricultural Water Management
Growers in arid regions often estimate soil water depletion (Dr) of the root zone in making irrigation scheduling decisions. While growers might use soil water sensors, actual Dr in fields may be only vaguely assessed.

OpenET: Filling a Critical Data Gap in Water Management for the Western United States [PDF]

JAWRA Journal of the American Water Resources Association, 2021
AbstractThe lack of consistent, accurate information on evapotranspiration (ET) and consumptive use of water by irrigated agriculture is one of the most important data gaps for water managers in the western United States (U.S.) and other arid agricultural regions globally.

Crop water use dynamics over arid and semi-arid croplands in the lower Colorado River Basin

European Journal of Remote Sensing, 2023
Numerous studies have evaluated the application of Remote Sensing (RS) techniques for mapping actual evapotranspiration (ETa) using Vegetation-Index-based (VI-based) and surface energy balance methods (SEB).
