The discovery of a new sulfur molecule during the third leg of NASA ATom mission in 2017 raises many questions about our understanding of the marine sulfur cycle, which influences oceanic cloud formation. The left side of the diagram shows two primary reaction products of DMS, SO2 and MSA, and the newly discovered molecule, HPMTF. On the right, new research suggests that on average 30 percent of DMS becomes HPMTF. Image credit: Patrick Veres/NOAA.
