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 (τ_a/τ_R), absorbing and scattering constituent components (τ_κ/(τ_a + τ_R)), and single scattering albedo omega of aerosol constituent ratio (where τ_a, τ_R are aerosol and gas components, and τ_κ is absorbing component of effective optical depth of the formation of the intensity of diffuse reflected radiation). The average value of the ratio τ_a/τ_R is 0.96 but it decreases slowly in the spectral region from 350 to 450 nm.
