A behavior with depth in the Jovian atmosphere for the values of aerosol volume scattering coefficient was shoved. The absorption in the continuous spectrum considered, thanks to the use the method of separation an aerosol and gas absorption during the calculations. We used the data of spectrophotometric measurements of Jupiter in the methane absorption bands on 727 and 619 nm — geometrical albedo in 1993 and reflectivity for a number of latitudinal strips in 2013. The dependences of for the integral disc and in the latitudinal strips of the planet-giant, on the altitude levels of a troposphere in the pressure range 0.4—2 bar, was similar. The three most powerful cloud layers with a maximum value of coefficient in the pressure range from 0.8 bar in the strip NTB to 1.33 bar in the STB was found in this part of the atmosphere. The fourth, enough powerful cloud layer in the pressure range of 2—4 bar in all investigated bands, except NTB and STB, was detected. The altitude level and the vertical structure of this layer are significantly different. We have found a possible another layer on the great depths, the initial level and length of which in latitudinal bands also differ. A spectral dependence of in the most of the investigated latitudinal bands was been manifested deeper then 3 bars level. This probably indicates a change in the size of aerosol particles.
