Experimental results are presented on amplitude fluctuations of radio waves at the wavelength lambda equals 32cm, obtained during 32 measuring periods by radio wave occultation of the atmosphere on the dark and the illuminated sides of the planet. The experiments were conducted between October 28 and December 7, 1975 and during March, 1976 with the help of space probes ″Venera-9″ and ″Venera-10″ .
