Abstract

An iterative method for deducing the general temperature and moisture structure of the troposphere from satellite radiation measurements of medium spectral resolution is described. The temperature and moisture profiles derived from simulated and radiometrically observed radiances, pertaining to clear atmospheres, are shown to agree favorably with the radiosonde profiles. The method is expanded to enable the inference of the temperature and moisture profiles of partly cloudy atmospheres. The ability of the method to recognize severe noise in radiance observations which lead to unacceptable temperature and moisture solutions is demonstrated.
