An Atmospheric Temperature Profile Measured with an In-Situ Infrared Radiometer.

Abstract

A side-looking infrared radiometer operating in a narrow spectral interval in the 15 micrometers carbon dioxide band was flown on a balloon platform. Data were obtained over the altitude range from 9.4 to 30 km. The resulting radiance measurements are compared with calculations making use of independent rawinsonde measurements obtained during the balloon flight. These comparisons indicate a systematic discrepancy of a few percent at lower altitudes increasing to 20 percent near 20 km. This discrepancy is found to be consistent with a previous study of satellite based radiances. Possible sources of this discrepancy are investigated and rejected, leading the authors to question the assumption that the source function is equal to the Planck intensity. (Author)
