Abstract: A method for optical parameter estimation of the nonisothermal giant planet atmospheres is developed by using detailed intensity data on Raman scattering. Morozhenko's method was taken as a basis. Using observational data on Uranus's atmosphere, the spectral values for ratio of the components of the optical depth were obtained, namely, aerosol and gas components (τa/τR), absorbing and scattering constituent components (τκ/(τa + τR)), and single scattering albedo omega of aerosol constituent ratio (where τa, τR are aerosol and gas components, and τκ is absorbing component of effective optical depth of the formation of the intensity of diffuse reflected radiation). The average value of the ratio τa/τR is 0.96 but it decreases slowly in the spectral region from 350 to 450 nm. |
