Photochemistry of the Venus Atmosphere
نویسنده
چکیده
Carbon monoxide, produced in the Venus atmosphere by photolysis of C02, is removed mainly by reaction with OH. The radical OH is formed in part by photolysis of H 20., in part by reaction of 0 with H02 • Photolysis of HCl provides a major source of H radicals near the visible clouds of Venus and plays a major role in the overall photochemistry. The mixing ratio of 0 2 is estimated to be approximately 10-7, about a factor of 10 less than a recent observational upper limit reported by Traub and Carleton. A detailed model, which accounts for the photochemical stability of Venus C02, is presented and discussed.

Atmospheric Composition, Chemistry, and Clouds
Venus’ atmosphere has a rich chemistry involving interactions among sulfur, chlorine, nitrogen, hydrogen, and oxygen radicals. The chemical regimes in the atmosphere range from ion-neutral reactions in the ionosphere to photochemistry in the middle atmosphere to thermal equilibrium chemistry and surface-atmosphere reactions in the lower atmosphere. This variety makes Venus an important planet t...
متن کاملPhotochemistry of the Stratosphere of Venus : Implications for Atmospheric Evolution " 2 YUK L . YUNG
The photochemistry of the stratosphere of Venus was modeled using an updated and expanded chemical scheme, combined with the results of recent observations and laboratory studies. We examined three models, with H2 mixing ratio equal to 2 x 10 3, 5 x 10t, and I x 103, respectively. All models satisfactorily account for the observations of CO, 02, 0 2 CA), and SO2 in the stratosphere, but only th...
متن کاملEvidence for carbonyl sulfide (OCS) conversion to CO in the lower atmosphere of Venus
[1] The chemical regimes in the atmosphere of Venus vary from photochemistry in the middle atmosphere to thermal equilibrium chemistry in the lower atmosphere and the surface. Many chemical cycles have been proposed, but few details about these cycles are fully verified by comparison between observations and modeling. Recent high-quality data of carbonyl sulfide (OCS) and CO from ground-based a...
متن کاملDetermination of O2(a1 delta g) and O2(b1 sigma+ g) yields in the reaction O + ClO --> Cl + O2: implications for photochemistry in the atmosphere of Venus.
A discharge flow apparatus with chemiluminescence detector has been used to study the reaction O + ClO --> Cl + O2, where O2 = O2(a1 delta g) or O2(b1 sigma+ g). The measured quantum yields for producing O2(a1 delta g) and O2(b1 sigma+ g) in the above reaction are less than 2.5 x 10(-2) and equal to (4.4 +/- 1.1) x 10(-4), respectively. The observed O2(a1 delta g) airglow of Venus cannot be e...
متن کاملLaboratory Studies on the Reactions between Chlorine, Sulfur Dioxide, and Oxygen: Implications for the Venus Stratosphere 1
The title reaction was studied by photolyzing mixtures of CI2 and SO2 with and without 02 present in an atmosphere of N2, using Fourier transform infrared spectrophotometry to monitor reactants and products. In the absence of oxygen, sulfur dioxide is quantitatively converted to sulfuryl chloride. With 10 to 150 Torr 02 present H2SO4 is produced as well as SO2C12. When a number of speculative r...
