SIO Reference 58-42. A simple model for radiance distributions in optically deep natural hydrosols is derived from the equation of transfer* for radiance Using a special form of the path function derived from the classical two-flow Schuster differential equations for irradiance. The model yields explicit expressions for the apparent radiance of submerged objects and the contrast transmittance for arbitrary paths of sight in the hydrosol. The model reproduces the major features of experimentally determined radiance distributions under a variety of external lighting conditions.
