Estimating Transpiration from Turfgrass Using Stomatal Conductance Values Derived from Infrared Thermometry
Evapotranspiration, evapotranspiration models, water
Infrared thermometry provides accurate measurements of plant canopy temperature, which, along with basic weather variables, allows estimation of canopy stomatal conductance to water vapor flux (gc) and transpiration. Using this method we compared modeled estimates of transpiration (CONDT) with evapotranspiration (ET) measurements from nearby microlysimeters (LYSET) in tall fescue (Schedonorus arundinaceus Schreb.) turfgrass. Results indicated transpiration may be reliably estimated via calculation of gc in turfgrass.
