Conteúdo: | The purpose of this study was to develp a procedure for the calibration of an infrared thermometer used for measurement of soil and plant-canopy temperatures. Three infrared thermometers were calibrated for surface-temperature measurements using an ice and a heated water bath. The infrared thermometers were also checked for linearilty of surface temperature measurements. The surface minus air-temperature readins were calibrated using and aluminum-foil-lined cardboard box. The effects of shadows on surface minu sair temperature measurements were also studied. The results for calibrating  surface and surface-minus-air temperatures proved satisfactory. Also, the linearity of the infrared thermometers was determined to be within the mafacture's claimed limits.
