Results of a field experiment on studying solar radiation passing in the visible wavelength range are described with the model
aerosol media created in the surface atmosphere. High-efficiency thermocondensation generators were used for creating model
aerosol media. The index of refraction and an average size of the aerosol particles formed are close to those characteristic
of the natural stratospheric aerosol. The composition and technical characteristics of the equipment complex used in the experiments
to control aerosol optical and microphysical parameters and meteorological conditions of the experiment are considered. The
Gaussian model of impurity dispersion in the boundary layer is used for the analysis and interpretation of measurement results.
It is found that with a number concentration of aerosol particles of ∼10
2–10
3 cm
−3 (which corresponds to the aerosol density in the deposited layer of about 1–10 mg/m
2 with the layer thickness along the ray path of about 100 m) the solar radiation attenuation with artificial aerosol layers
accounts for 1 to 10%. Model estimates are in satisfactory agreement with the measurement results.
