Two iterative methods for inverting the integral form of the radiative transfer equation to obtain temperature profiles from satellite infrared radiance measurements were subjected to a detailed analytical investigation. The two methods are the minimum information method and Smiths direct method. Under the assumption that the radiance measurement errors were Gaussian with mean zero and known variance, each method was investigated to determine the effects of these errors upon the retrieved temperatures. The convergence characteristics and frequency response to differences between the true temperature profile and the first guess temperature profile were investigated for each method. Details of the investigation and the results are presented in the report. Author
