TL;DR: In this article, the authors assess PM1 pH as a function of geographical location and altitude, focusing on the northeastern US, based on aircraft measurements from the Wintertime Investigation of Transport, Emissions, and Reactivity (WINTER) campaign (01 Feb to 15 Mar 2015).

TL;DR: One year of aerosol particle observations from Alert, Nunavut shows that new particle formation (NPF) is common during clean periods of the summertime Arctic associated with low condensation sinks and with the presence of methane sulfonic acid (MSA), a product of the atmospheric oxidation of dimethyl sulfide (DMS).

TL;DR: Simulations that reproduce detailed airborne observations of wintertime atmospheric chemistry over the eastern United States indicate that particulate sulfate and nitrate formation is limited by the availability of oxidants and by the acidity of fine particles, respectively, and that larger emission reductions are necessary for substantial improvements in wintertime air quality.

TL;DR: The atmospheric discovery of a previously unquantified DMS oxidation product, hydroperoxymethyl thioformate (HPMTF, HOOCH2SCHO), identified through global-scale airborne observations that demonstrate it to be a major reservoir of marine sulfur.

TL;DR: In this article, the authors investigate the contribution of transported organic aerosol (OA) to total loadings observed over Seoul by using observations over the Yellow Sea coupled to FLEXPART Lagrangian simulations.
