SCATTERING AND POLARIZATION PROPERTIES OF POLYDISPERSED SUSPENSIONS WITH PARTIAL ABSORPTION
Abstract
The angular scattering and polarization properties of polydispersed suspensions of nonabsorbing and partially absorbing spheres have been computed using the complete Mie series. The results with three types of size distributions are presented and compared with observations. These show a strong dependence of angular intensity and polarization patterns on the size distribution, the size range, and the dielectric and absorbing properties of the individual particles. A peculiarity of scattering at angles near 45 degrees, observed experimentally and independently by two authors, is corroborated by the numerical results. Prominent observational features characteristic of natural fog, such as an extremely bright aureole, rainbows and counter coronas are reproduced in a model corresponding to a cloud of spherical water droplets, with a wide distribution in droplet radius and a maximum concentration at a 4-micron radius.
