Recent models for the chemical composition of the atmosphere of Venus are reviewed. It is found that the sulfuric aerosol model corresponds best with the observational data in accounting for the composition of the cloud cover. The role of sulfur is discussed with attention to the regeneration of CO2, and the generation and dissolution of the aerosol particles. It is shown that sulfur helps to regulate the oxidation-reduction regime in the surface rock-troposphere system. The downward and upward gaseous fluxes in the subcloud troposphere are distinguished, the downward flux transporting high concentrations of water vapor, and the upward flux transporting gaseous products of the interactions of the near-surface atmosphere with surface rocks as well as gases from below the surface. It is demonstrated that sulfur may be fixed in the core rocks in the forms of pyrite and anhydrite.
