Abstract

Observation material of 1993 - 1995 seasons is reduced and optical characteristics of upper atmosphere of the Earth are obtained, and namely: height indicatrices of terrestrial atmosphere scattering and volume coefficient of scattering. For wavelengths 754 nm and 585 nm indicatrices of scattering are obtained for height 10, 20, . . ., 80, 100 km above the ground level whereas for 356 nm indicatrices for height 30, 40, . . . 80, 100 km are obtained. Indicatrices are typically most extended at small height (10 - 40 km) and more sloping at heights 90 km and more at small height antropogeneous and heterogeneous dust is accumulated. This dust concentration diminishes with height and at those of 50 - 80 km a relative purification of the Earth's atmosphere from the dust constituent takes place. At heights over 80 km a considerable contribution is made to scattering by the cosmic dust influx.
