Résumé

The multiresolution radiative transfer equations of Part I of this paper are solved numerically for the case of inhomogeneous model clouds using Meyer's basis functions. After analyzing the properties of Meyer's connection coefficients and effective coupling operators (ECOs) for two examples of extinction functions, the present approach is validated by comparisons with Spherical Harmonic Discrete Ordinate Method (SHDOM) and Monte Carlo codes, and a preliminary analysis of the local-scale coupling between the cloud inhomogeneities and the radiance fields is presented. It is demonstrated that the contribution of subpixel-scale cloud inhomogeneities to pixel-scale radiation fields may be very important and that it varies considerably as a function of local cloud inhomogeneities.
