We present and validate a new network of atmospheric thermochemical and photochemical sulfur reactions. We use a 1D chemical kinetics model to investigate these reactions as part of a broader HCNO chemical network in a series of hot and warm Jupiters. We find that temperatures approaching $1400\, \mathrm{K}$ are favourable for the production of H2S and HS around $\mathrm{10^{-3}\, bar}$ at mixing ratios of around 10−5, an atmospheric level where detection by transit spectroscopy may be… 
A Comparative Study of Atmospheric Chemistry with VULCAN
We present an update of the open-source photochemical kinetics code VULCAN to include C–H–N–O–S networks and photochemistry. The additional new features are advection transport, condensation, various
Photochemistry of Venus-like Planets Orbiting K- and M-dwarf Stars
Compared to the diversity seen in exoplanets, Venus is a veritable astrophysical twin of the Earth; however, its global cloud layer truncates features in transmission spectroscopy, masking its
Spectroscopic Characterization of HSO2• and HOSO• Intermediates Involved in SO2 Geoengineering.
Assignment of the UV-vis spectra is consistent with the photochemistry of HOSO• and HSO2• as observed by matrix-isolation IR spectroscopy and also by the agreement with high-level ab initio calculations.

A connection between climate and marine algae comes from the algal production of a sulphur-containing compound, dimethylsulphoniopropionate, and the action of one of the resulting products as a defence mechanism is described.
