Calculated mie scattering properties in the visible and infrared of measured los angeles aerosol size distributions.

Aerosol size distributions of varying types selected from those measured in clear air, smog, and fog in the Los Angeles Basin have been used with Lorenz-Mie scattering theory to predict radiation scattering by aerosols. Eleven different indices of refraction were assumed for wavelengths from 0.488 microm to 8.4 microm for aerosol materials with varying humidity, and for water and quartz. The effect on the scattering by the type of size distribution and the complex index of refraction is shown as a function of the polarization parameters of polarization, polarization ratio, ellipticity, and the inclination angle of the polarization ellipse.
