Empirical Investigation of Three Iterative Methods for Inverting the Radiative Transfer Equation,
ARMY ELECTRONICS COMMAND FORT MONMOUTH N J
Pagination or Media Count:
Three 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 empirical investigation. The methods are a minimum information method, b Smiths direct method, and c Duncans modification of Smiths direct method. Each method was examined for a rate of convergence, b frequency response to differences between the first guess temperature profile and the true temperature profile, and c the effects of noise on the radiance measurements. Details of the investigation and the results are presented in the report.
