An iterative technique for the retrieval of temperatures at each of 100 levels ranging from 1000 mb to 0.01 mb is evaluated. Clear-column radiance data in the carbon dioxide channels of the Vertical Temperature Profile Radiometer VTPR of NOAA 2 are used in inverting the radiative transfer equations to deduce the TP profile. The retrieval technique includes the computation of atmospheric transmittances due to three atmospheric absorber masses carbon dioxide, water vapor, and ozone and non-homogeneous temperature-pressure effects along the vertical. The program also corrects these transmittances for zenith path differences between the satellite and the retrieval site when the site is not directly below the sensor.
