Sulfur chemistry in the Venus mesosphere from SO 2 and SO microwave spectra

Sandor, Brad J; Clancy, R. Todd; Moriarty-Schieven, Gerald; Mills, Franklin


First measurements of SO2 and SO in the Venus mesosphere (70-100km) are reported. This altitude range is distinctly above the ~60-70km range to which nadir-sounding IR and UV investigations are sensitive. Since July 2004, use of ground-based sub-mm spectroscopy has yielded multiple discoveries. Abundance of each molecule varies strongly on many timescales over the entire sub-Earth Venus hemisphere. Diurnal behavior is evident, with more SO2, and less SO, at night than during the day....[Show more]
