Kostogryz N. The aerosol components of Uranus' atmosphere using Raman scattering data.

The investigation of Raman scattering influence in the planetary atmosphere with accounting their observational temperature-depth dependence was taken in the PhD Thesis. As a result of our investigations, a new mechanism of the atmospheric optical parameters determinations using Raman scattering data with taken into account the temperature profile of Uranus' atmosphere was developed. We obtained that when we didn't take into account the temperature-depth dependence in the giant planet atmospheres, we've got the huge errors in the atmospheric optical parameters determinations, such as the ratio of aerosol to gas scattering components of the optical depths and also the ratio of absorbing to scattering components of the optical depths. As Raman scattering effects in the giant planet atmospheres lead to geometric albedos and also single scattering albedos decreasing in the blue spectral region, so we've determined the values of the single scattering albedos which are corrected for Raman scattering effects.The possible reason of long-period variations of the geometric albedos of Uranus was investigated. Leading our modeling and applying our method to the different year observational data (1981, 1993, 1995), we revealed the optical parameters of Uranus' atmosphere changing with a time and also with Uranus' position on its orbit. There were analyzed the contemporary photometric observations of Uranus' disc which were obtained with the largest telescopes of all world and which registered appearance and disappearance of the aerosol clouds on the difference latitudes. We proposed the conclusion that exactly heterogeneous aerosol distribution in the Uranus' atmosphere on the difference latitudes may be the possible reason of the long-period geometric albedos variations.
