Research Project: Estimating Evapotranspiration and Plant Water Stress with Remote Sensing

Location: Water Management Research

Project Number: 5402-13000-007-05
Project Type: Specific Cooperative Agreement

Start Date: Sep 01, 2013
End Date: Sep 30, 2015

Use remote sensing techniques at multiple scales to predict plant stress and evapotranspiration of deficit-irrigated crops.

Thermal, near infrared, and visible band reflectance will be collected of full and deficit irrigated crops at the ARS Limited Irrigation Research Farm. These reflectance measurements will be compared with other measures of water availability and plant stress collected by ARS and relationships will be developed. One potential technique will be to use Crop Water Stress Index with thermal infrared reflectance and ground-based weather parameters as a stress and ET index.
