Abstract

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 ((phi) equals 43 degrees), July ((phi) equals 39 degrees) and August ((phi) equals 37 degrees). The equation composition of the radiation balance from varies cloud forms and transparence atmosphere in the wavelength range 0.38 to 0.71 micrometer on latitude 40 - 41 degrees is given. The hard aerosol pollution decreases the direct solar radiation by 10 - 15%.
