Aerosol Phase Functions: Models and Measurements

摘要

A dual wavelength polar nephelometer has been developed to measure the angular scattering properties of the natural atmosphere at 1.06 microns and 10.6 microns. A brief description of the nephelometer will be given. The results of a series of field measurements with the nephelometer and supporting meteorological measurements will be presented. Comparisons between the measurements and theoretical phase functions for models of the atmospheric aerosols will be discussed. The model phase functions will then be used to extend the discussion of the aerosol angular scattering to other wavelengths.
