Evaluate and refine thermal-based remote sensing models and develop operational 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 Utah State University (Cooperator). The remote sensing imagery from UAS-Unmanned Aerial System 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 phenological stages. The high resolution UAS 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.
