Abstract
Apparatus and methods are disclosed for enhancing data accuracy of a noncontact infrared thermometer. One method includes determining dry atmospheric constituency and water vapor absorption coefficients across the infrared thermometers spectral bandpass and implementing the coefficients in processing with site-based atmospheric temperature and water vapor density profile and pressure measurements to provide corrected target temperature data compensating for contamination in said raw data due to said intervening atmosphere. The method is particularly well adapted for use in correcting data from less expensive but also less accurate wideband infrared thermometers.
