Measurement of Lower Atmospheric Temperature Profiles from Ground-Based Infrared Observations.
Abstract
A ground-based infrared spectroradiometer has been used to measure the vertical temperature profile of the lower atmosphere from 0 to 6 km. Eight measurements in the 15-m carbon dioxide band have been used for the inversion in addition to three measurements in the 18-m water vapor band for the water vapor corrections. One additional observation in the 11-m window region is used to determine the presence of cloud. Twenty-one sets of clear sky data obtained in the summer of 1971 are used to verify the inversion technique. The resultant profiles have an accuracy comparable to that of radiosondes with an overall rms error of 1.58°C.
