Abstract: A changes of the behavior with depth of the aerosol and the gas scattering components of the effective optical depth in the profiles of 887, 864, 842, 727 and 619 nm spectral absorption bands of atmospheric methane has been received. A model of homogeneous spherical aerosol particles was in use. The values of particles parameters are near to real values for altitude levels with pressure range of 0.18...1.5 bar. A presence of the stratospheric aerosol has been detected at 0.054 bar and at higher altitude levels. At least seven features are defined in the vertical structure of cloud cover in the upper part of the atmosphere of Saturn. The altitude position of the highest relative aerosol concentration has been determined at a level with pressure of about 0.3 bar, at a relative methane concentration of 0.0021, and about 0.12 bar at 0.0533. It was found that at the altitude levels with pressure > 0.44 bar there was a presence of a cloud that is stretched along a height and without selected aerosol layers inside. The signs of possible changes of aerosol particles parameters was been detected in the deep levels from the pressure value of 1.5 bar and more. |
