Abstract: 

With using of measured data of geometric albedo of Jupiter in 1993 in the absorption bands of methane on 619, 727 and 842 nm, a dependence with pressure of the volume scattering coefficient of aerosol was been calculated. In the deep layers of atmosphere with 4.0...14.0 bars pressure levels a possible changes of aerosol particles parameters was been found. For the first time, we determined possible changing values of those parameters. For the specified depth range in the atmosphere, we observed a nearly two fold and more increasing (up from 0.73 micrometers) of the effective radius of aerosole particles, and increasing of nearly 10 % of the value of real part of the refractive index (more then 1.44), in comparing with the same values in the upper part of the planet’s atmosphere. With using of mentioned parameters, no presence of aerosole layer in the deep levels of Jovian atmosphere was been founded.
