Fig. 2. Energy balance of well-watered and water-stressed winter wheat under (A) high and (B) moderate evaporative demand at Bushland Texas. Evaporation (LE) was measured by weighing lysimeters, R_n by net radiometer, G by heat flux plates corrected for heat storage above the plates, and sensible heat (H) by solution of Eq. [1]. Last rainfall of 12.2 mm (29.9 MJ m^–2 equivalent) was May 2. Data source: Collaborative research of J.L. Steiner, T.A. Howell, A.D. Schneider, S.R. Evett, and J.A. Tolk, USDA-ARS, Bushland, TX.
