The method for determining of value the imaginary part of the complex refractive index of aerosol particles, they forms a cloudy layer, which lays in a particular altitudes level of giant planet’s atmosphere, was been developed. We have calculated the value of for both the whole atmospheric column and for the separate cloudy layer with using of spectral data of geometric albedo of Jupiter in 1993. The mentioned cloudy layer has a pressure range of 0.52—0.78 bars and may be compose of hydrosulfide ammonium. The values of obtained for the cloud layer and for the entire atmospheric column differ quite substantially: 0.00098 and 0.00012, respectively.
