Ovsak O. The parameters determination for the vertical structure of aerosol component in atmospheres of Giant planets.

The thesis is devoted to the development of an algorithm of model calculations and to the analysis of spectrophotometric measurements the intensity radiation diffuse reflected by the atmospheres of Giant planets in the molecular absorption bands of atmospheric gases. The computer program complex aimed at calculation of values of the effective optical depth was created. This is an optical depth forming the intensity of the light which is diffusely reflected by the homogeneous semi-infinite cloudy layer with a random optical properties. The complex is based on the exact solution of the task about the light which is diffusely reflected by the homogeneous semi-infinite medium. The values of effective optical depth for isotropic and anisotropic light scattering cases was been calculated. The dependencies this value according to the optical parameters of the studied media investigated. There were found the level heights of Jupiter's atmosphere with a maximal aerosol density and the stratification of aerosol particles by sizes. There were detected a changes of scattering characteristics as well as a dynamic characteristics of the Jupiter's atmosphere at the impact place of the fragment K of a comet Shoemaker-Levy 9. It is established a view dependences on the height for a changes of aerosol component of optical thickness as well as for a volume scattering coefficient in the atmospheres of Jupiter, Saturn, Uranus and Neptune. The pattern of dependence on the height for a change of the methane relative concentration in the atmospheres of Uranus and Neptune was refined.
