Description

Eighteen infrared thermometers (IRTs) were used to monitor cotton canopy temp. for an entire growing season. The IRTs were calibrated in the field on 5 dates and compared with the manufacturer's calibration. Individual periodic calibration was needed for accuracies better than 2°C. Canopy temp. measured with a hand-held IRT that scanned the canopy vs. a fixed-position IRT differed by 0.5°C
