Abstract

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 (g_c) and transpiration. Using this method we compared modeled estimates of transpiration (COND_T) with evapotranspiration (ET) measurements from nearby microlysimeters (LYS_ET) in tall fescue (Schedonorus arundinaceusSchreb.) turfgrass. Results indicated transpiration may be reliably estimated via calculation of g_cin turfgrass.
