Refractive index and size distribution of aerosols as estimated from light scattering measurements.

Abstract

Angular distributions of the intensity of light scattered by airborne particles were measured for both parallel and perpendicularly polarized components. A precision polar nephelometer was constructed for use of this study. The size distribution of aerosols can be approximated by the log-normal distribution function; the mean radius and the standard deviation are found to be rg = 0.138 micrometer and sigmag = 2.56, respectively, as geometrical mean values for the whole data. -from Authors
