Abstract
Airborne measurements of atmospheric-path transmission and atmospheric-path (up-welled) radiance in the 8 to 14 μm band were obtained by applying a multiple-altitude and a dual view angle calibration technique to thermal infrared line scanner data. Spectrally corrected LOWTRAN was used to generate path transmission and up-welled radiance values corresponding to the empirical measurements. Using LOWTRAN and the multiple-altitude method, calibration of the thermograms to account for atmospheric effects yields computed surface temperatures within 0.7°C of concurrent kinetic temperature readings. The angular calibration method results in similar computed surface temperature errors for 1000 ft altitude data and increasing by 1.2°C per 1000 ft up to a 6000 ft altitude. This paper contains the results of a comparative analysis of these approaches for atmospheric calibration.
