Research Project: Mapping Evapotranspiration and Stress Over Vineyards Using High Resolution Thermal Remote Sensing 1 IOP

Location: Hydrology and Remote Sensing Laboratory

Project Number: 8042-13610-028-52-S
Project Type: Non-Assistance Cooperative Agreement

Start Date: Apr 1, 2013
End Date: Mar 31, 2015

Evaluate and refine thermal-based two-source remote sensing models and tools for quantifying water use (evapotranspiration) and root zone water availability and stress of vineyards for improved water management while maintaining grape productivity and quality.

Conduct intensive field experiments collecting evapotranspiration (ET), root zone soil moisture, and biophysical data in concert with high resolution aircraft remote sensing imagery provided by the Cooperator. The remote sensing imagery from aircraft and satellite sensors will be used to evaluate and refine remote-sensing-based ET models for quantifying vineyard water use and vine stress/condition at different vine physiological stages. The high resolution aircraft imagery will be used to distinguish vine and cover crop contributions to total water use and root zone water availability as well as the capability of using coarser resolution satellite data with thermal sharpening techniques to provide separate vine and cover crop contributions to total ET.
