Research Project: Development of a Low-Cost and Accessible Evapotranspiration Toolkit for Irrigation Management of Woody Crops

Location: Crops Pathology and Genetics Research

Project Number: 2032-21220-008-046-S
Project Type: Non-Assistance Cooperative Agreement

Start Date: Feb 1, 2021
End Date: Dec 31, 2022

Validate crop evapotranspiration (ET) model outputs determined from on satellite thermal imagery. Outputs are embedded within the OpenET platform, which is a low-cost, accessible, and spatially distributed data at sub-field resolutions based on an ensemble of crop ET models. OpenET will be operational in December 2020, but rigorous validation of its woody tree crop ET estimates has yet to occur.

Working closely with industry partners, this project will use an approach similar to GRAPEX but adapted for commercial almonds to ground truth data from OpenET and to train stakeholders on its use. Personnel efforts will include establishment and maintenance of flux towers, ground –based physiological stress evaluation and energy balance partitioning, and new computational methods to handle remotely sensed data.
