Absorption of the salar radiation in the atmosphere in Central Asian region

The total energetic exposition on a horizontal surface at the top of the atmosphere in different seasons of a year at the latitude of 30 to 45 degrees is estimating. Cloudiness decreases the direct solar radiation on a horizontal surface by 10-15% (upper clouds level), by 20-25% (middle clouds level) and by 30-35% (lover clouds level). In Central Asian region the direct solar radiation flux decreases with increase latitude by 37% (winter), by 25% (autumn) and by 10% (spring). In summer season the direct solar radiation flux increase in June (p=43 degrees), July (p=39 degrees) and August (p=37 degrees). The equation composition of the radiation balance from varies cloud forms and transparence atmosphere in the wavelength range 0.3 8 to 0.71 mum on latitude 40-41 degrees is given. The hard aerosol pollution decreases the direct solar radiation by 10-15%.
