Scattering in thick multifractal clouds, Part I: Overview and single
scattering scattering in thick multifractal clouds.

Abstract
Over the last twenty years, many studies have been made of radiative transfer in scaling cloud
fields, the vast majority of which have been limited to numerical studies in clouds with relatively
small optical thickness. An exception to this was the development of a formalism for treating single
scattering in optically thick but conservative multifractal clouds without significant holes. In part I of
this paper we show how these results can be extended to general "universal" multifractal clouds
dominated by low density «Lévy holes». In part II, we demonstrate how the analytic single
scattering results can be generalized to multiple scattering including the case of very thick clouds
as well as to realistic nonconservative clouds.
