Estimating irrigation water use from remotely sensed evapotranspiration data: Accuracy and uncertainties at field, water right, and regional scales

Agricultural Water Management
Irrigated agriculture is the dominant user of water globally, but most water withdrawals are not monitored or reported. As a result, it is largely unknown when, where, and how much water is used for irrigation.

A comparative analysis of OpenET for evaluating evapotranspiration in California almond orchards

Agricultural and Forest Meteorology
The almond industry in California faces water management challenges that are being exacerbated by droughts, climate change, and groundwater sustainability legislation. The Tree-crop Remote sensing of Evapotranspiration eXperiment (T-REX) aims to explore opportunities to improve precision irrigation management for woody perennial cropping systems ...

ECOSTRESS Evapotranspiration Estimates Across Temporal and Spatial Scales in Arid and Semi‐Arid Southern Arizona, USA

Journal of Geophysical Research: Biogeosciences, Volume 130, Issue 12, December 2025.
Abstract Evapotranspiration (ET) is the largest outgoing water flux in the hydrologic cycle but the most difficult component to quantify. In arid and semi‐arid regions, ET can be up to 99% of precipitation and thus critical for land and water managers to quantify accurately.

Field-scale water use assessment in the Lower Mississippi Alluvial Plain using OpenET

International Journal of Applied Earth Observations and Geoinformation
Water scarcity and unprecedented rapid depletion of groundwater reserves are challenges for global sustainable agricultural development. Understanding water usage is especially critical in key agricultural production regions.

The Role of Spatial Water Right Data in Understanding Anthropogenic Effects on the Water Balance

JAWRA Journal of the American Water Resources Association, Volume 61, Issue 6, December 2025.
ABSTRACT Water regulation, extraction, and application have major effects on water availability. We investigated the impact of anthropogenic water use on the water balance in two intensively irrigated headwater watersheds in Wyoming using geospatially comprehensive water right data in a watershed hydrologic‐allocation modeling framework.

James Buttle Review: Dynamic Water Storage Shapes Critical Zone Function in Snow‐Dominated Mountain Watersheds

Hydrological Processes, Volume 39, Issue 11, November 2025.
Dynamic storage in snow‐dominated mountain systems includes snowpacks, plant accessible water (PAW), groundwater and surface. We summarise recent advances in measuring and modelling these dynamic stores. Our review highlights spatial heterogeneity and time evolution of capacity and filling/depletion of these stores and discusses implications for ...

Data‐Model Integration to Unravel Critical Zone Dynamics: Challenges, Successes, and Future Directions

WIREs Water, Volume 12, Issue 6, November/December 2025.
A three‐tiered example of data‐model integration for understanding dissolved organic carbon and stream discharge dynamics. ABSTRACT In the Anthropocene—a period marked by rapid environmental change—understanding the critical zone (CZ), the Earth's outer layer where rock, soil, water, air, and living organisms interact, is crucial.

Assessing the accuracy of OpenET satellite-based evapotranspiration data to support water resource and land management applications

Nature Water
This talk will give an overview of the recent accuracy assessment of the [OpenET](https://etdata.org/) remote sensing evapotranspiration (ET) data production platform. OpenET ET data accuracy was evaluated using direct comparisons with high quality *in situ* ET observations from 152 stations (primarily eddy covariance systems) across the contiguous ...

Regional Variations in Drivers of Extreme Reference Evapotranspiration Across the Contiguous United States

Water Resources Research, Volume 61, Issue 10, October 2025.
Abstract Extremely high reference evapotranspiration indicates an abnormal atmospheric water demand, with significant implications for regional water resource management. Despite its importance, our understanding of extreme reference evapotranspiration remains limited, particularly regarding the contributions of its underlying drivers.

Greater Rock Moisture Deficits on a Pole‐Facing Hillslope Due To Aspect‐Related Variations in Vegetation Water Use

Geophysical Research Letters, Volume 52, Issue 17, 16 September 2025.
Abstract Water stored in weathered bedrock plays a crucial role in the terrestrial water cycle by influencing vegetation, streamflow, and groundwater recharge. Past studies on the impact of aspect‐driven differences in insolation quantify moisture in shallow soils but largely ignore moisture dynamics in deeper weathered bedrock.
