Radiative transfer in the surfaces of atmosphereless bodies. III. Interpretation of lunar photometry.
Abstract
Narrowband and UBV photoelectric phase curves of the entire lunar disk and surface photometry of some craters have been interpreted using a newly developed generalized radiative transfer theory for planetary regoliths. The data are well fitted by the theory, yielding information on both macroscopic and microscopic lunar properties. Derived values for the integrated disk geometric albedo are considerably higher than quoted previously, because of the present inclusion of an accurately determined opposition effect. The mean surface roughness, defined as the ratio of the height to the radius of a typical irregularity, is found to be 0.9 + or  0.1, or somewhat less than the mean value of 1.2 obtained for the asteroids. From the phase curves, wavelengthdependent values of the single scattering albedo and the HenyeyGreenstein asymmetry factor for the average surface particle are derived.
