Short summary

We develop an approach to determine the uncertainty in reactions involved in the breakdown of dimethyl sulfide and methanethiol in the atmosphere, and run simulations spanning temperate, tropical, and polar conditions to quantify the impacts of this uncertainty on the concentration of these sulfur species and their products. We extend this analysis to identify key reactions that drive the uncertainty and highlight areas for further experimental and theoretical work.
