Abstract

Temperatures derived from the 15-μ CO2 channel of the radiometer carried aboard the TIROS VII satellite were compared to the radiosonde temperatures at 100, 70, 50, 30, 20 and 10 mb at 97 stations in the Northern Hemisphere from 20 January to 17 February 1964. The 15-μ temperature is rarely colder than the 30-mb temperature, and it generally falls between the 10- and 30-mb temperatures. The highest correlation between 15-μ and radiosonde temperatures was 0.7 at both 30 and 20 mb, near the level of maximum weight which applies to the 15-μ radiance weighting function profile. The variation of 15-μ temperatures with longitude closely follows the variation of 10-100 mb thickness pattern.
