Technical Abstract: Field-grown grain sorghum [Sorghum bicolor (L.) Moench] was exposed to CO2 concentrations enriched to 200 umol/mol above ambient (ca. 370 umol/mol) using free-air CO2 enrichment (FACE) apparatus. Half of each main CO2 plot received ample water, while the other half received a deficit amount thereby exposing the plants to severe drought. Measurements were made of net radiation, canopy temperature, air temperature, soil heat flux, and wind speed. Energy balance components, including evapotranspiration were calculated from the data and comparisons made among the plots.
