LIGHT-SCATTERING MEASUREMENTS AND THE ANALYSIS OF NATURAL AEROSOL SIZE DISTRIBUTIONS

Abstract

Based on Mie's theory of light scattering by small particles, the optical properties of natural aerosol particles are analyzed. The scattering properties of water droplets (refractive index 1.33), aerosol particles (average refractive index 1.55) and the scattering and absorption properties of carbon particles (refractive index 1.6 - 0.66i) are discussed in detail. Complex scattering functions for power series size distributions have been computed, and results of some light-scattering-function measurements at Island Beach, New Jersey, are compared with the computed scattering functions.
