Abstract
In July-Aug. 1974, temperatures of soyabean, sorghum and Panicum miliaceum, grown in fields at Manhattan, Kansas, and Mead and Scottsbluff, Nebraska, were measured with a thermal scanner flown at altitudes of 610 or 1220 m and were used in a resistance form of the energy-balance equation to estimate evapotranspiration (Et). Equivalent black-body temperatures measured at 610 and 1220 m were 2-6 deg C lower than leaf surface temperatures measured by thermocouples. A correction procedure relating temperature error to atmospheric precipitable water was applied to the scanner measurements. Estimates of Et using the corrected temperatures differed from lysimetric measurements by from -0.4 to 0.17 ly/min
