Abstract
This paper reviews the derivation and validation of a model for beam propagation in aerosol media. The model is a paraxial approximation to the radiative transfer equation. The main feature is the representation of the power flux in the direction normal to the propagation axis by a diffusion process. Coupled partial differential equations are obtained for the forward and backward flux densities. The solutions are compared to beam profile and backscatter measurements performed in laboratory-generated water droplet clouds and to transmittance measurements in falling snow. The effects of optical depth, cloud inhomogeneity, wavelength and receiver field of view are studied. In all cases, the agreement between predictions and experimental data is very good.
