RADIATIVE-TRANSFER SINGLE-SCATTERING ALBEDO ESTIMATION WITH A SUPER-PADE APPROXIMATION OF CHANDRASEKAR H-FUNCTION

Three algorithms for evaluating the single-scattering albedo within an isotropically scattering, semi-infinite medium are developed for meas urements external to the medium with narrow and wide field-of-view det ectors. Two of the algorithms are iterative and require the computatio n of the Chandrasekhar H-function, which can be done with the super-Pa de approximation, while the third algorithm is an explicit one that re quires no iteration.
