An experimental and model approach has been used to study the NO{sub 2} vertical profiles and its effect on solar irradiance. The profiles of NO{sub 2} were obtained using gas analyzers, which had been installed at different levels at the Moscow State University (MSU) located at the south-western part of Moscow and at the Ostankino tower located at the north of Moscow up to the height of 350 m. Using these data diurnal and spatial variability of the NO{sub 2} content in the most polluted part of planetary boundary layer (PBL) has been analyzed within the large megalopolis. On the base of photochemical modeling we have simulated the diurnal cycle of NO{sub 2} vertical profiles for summer and winter conditions and have compared the results with the experimental ones. Using the RT modeling with input gaseous and aerosol parameters of the atmosphere obtained from the MSU Meteorological Observatory we have estimated the attenuation of spectral solar irradiance in UV and visible region of spectrum due to the NO{sub 2} content in the polluted atmosphere for different seasons.
