Abstract:

This paper concludes a series of publications (see Refs. 1 to 5) that deal with the construction of an empirical model of the aerosol optical characteristics in the visible and near IR regions for the low troposphere. The model proposed provides for reconstruction of the aerosol scattering coefficient profile. In so doing one needs for, as input data, the scattering coefficient value of the dry aerosol substance at the near ground level measured at the wavelength of 0.52 μm, relative air humidity, aerosol optical thickness, and mean temperature of air in the low troposphere. To estimate the entire set of optical characteristics, we suggest to use, as the first order approximation, a single parameter model of the near ground aerosol with the relevant corrections for the vertical profile σ(H).
