Paper Abstract

Atmospheric aerosols play important roles in climate radiative forcing as well as environmental issues. In addition to microphysical and optical parameters, its vertical distribution is also important for both surface visibility, transport and related boundary layer stratification. Satellite-borne instruments, such as MODIS, AVHRR have monitored global aerosol distribution, but ground-based optical remote sensing is still of significance for validation and more detailed observation, such as diurnal variation and vertical distribution. In this paper, numerical simulations are conducted for clear atmosphere with various vertical structures of atmospheric aerosols. The sun direct observation is used to derive aerosol optical depth. In sun-zenith principal plane, pairs of directional scattered radiances symmetrically to solar direction (i.e. scattering angles are same but one is near zenith and the other near horizon) may be used to derive aerosol’s vertical distribution.
