Sulfur monoxide dimer chemistry as a possible source of polysulfur in the upper atmosphere of Venus

Autor: Joseph P. Pinto, Jiazheng Li, Franklin P. Mills, Emmanuel Marcq, Daria Evdokimova, Denis Belyaev, Yuk L. Yung

Publikováno v: Nature Communications, Vol 12, Iss 1, Pp 1-6 (2021)

Photochemistry of sulfur species in the upper Venus atmosphere is not well understood and the identity of ultraviolet (UV) absorber(s) remain unknown. Here, the authors show that sulfur monoxide dimer chemistry is a possible source of polysulfur, whi

Spatial distribution of the infrared O2 (α1Δg) airglow in the night Venus hemisphere based on the SPICAV IR/VEX nadir observations in 2006-2014

Autor: Daria Evdokimova, Anna Fedorova, Denis Belyaev, Franck Montmessin, Oleg Korablev, Jean-Loup Bertaux

Introduction Infrared O2 (α1Δg) airglow at 1.27 μm on the night side of Venus was for the first time identified during ground-based observations in 1975 (Connes et al., 1979). The airglow reaches its maximal intensity at ~96 km. These altitudes co
