The researchers of the Institute for Atmospheric and Earth system research at the University of Helsinki have investigated how atmospheric particles are formed in the Arctic. Until recent studies, the molecular processes of particle formation in the high Arctic remained a mystery.
During their expeditions to the Arctic, the scientists collected measurements for 12 months in total. The results of the extensive research project were recently published in the Geophysical Research Letters journal.
The researchers discovered that atmospheric vapors, particles, and cloud formation have clear differences within various Arctic environments. The study clarifies how Arctic warming and sea ice loss strengthens processes where different vapors are emitted to the atmosphere. The thinning of sea ice enables more iodine emissions while broader open waters enable more emissions of sulfur-containing vapors.
