Abstract:
Two methods for estimating the unknown optical thickness of a homogeneous cloudy atmosphere using a ground-level downward radiance or irradiance measurement are presented. An iteration method incorporates an analytically-computed first derivative of the unknown that is obtained from the FN method of transport theory; sample results from a sensitivity analysis for the iteration scheme are included. A noniterative method derived from two analytical solutions of the equation of radiative transfer is also given – an asymptotic radiative transfer algorithm and a transport-corrected diffusion algorithm.
