The photochemistry of the Venus stratosphere is modeled using an updated and expanded chemical scheme along with the results of recent observations and laboratory studies. Three models, with H2 mixing ratio equal to 2 x 10 to the -5th, 5 x 10 to the -7th, and 1 x 10 to the -13th, respectively, are examined. All three models are found to satisfactorily account for the observations of CO, O2, O2(1Delta), and SO2 in the stratosphere, but only the last one may be able to account for the diurnal behavior of mesospheric CO and the UV albedo. Oxygen, derived from CO2 photolysis, is mainly consumed by CO2 recombination and oxidation of SO2 to H2SO4. The photolysis of HCl in the upper stratosphere provides a major source of odd hydrogen and free chlorine radicals, essential for the catalytic oxidation of CO. Oxidation of SO2 by O occurs in the lower stratosphere. The modeling reveals a number of interesting similarities, previously unsuspected between the chemistry of the stratosphere of Venus and that of the earth; photochemistry may have played a major role in the evolution of the atmosphere.
