Abstract: 

Using the method developed by ourselves and the observational data on Uranus geometric albedo in 1981, 1993, 1995, the spectral values of optical depth were obtained, namely, τa/τR and τk/τS (where τa, τR are aerosol and gas components, τS = τa + τR, and τk is absorbing component of effective optical depth of the formation of the diffuse reflected radiation intensity). It is found that these ratios are different for 1981, 1993, and 1995 years. This effect can be due to the horizontal inhomogeneity of aerosol component of optical depth over the Uranus disk.
