TL;DR: In this article, the authors compared the molecular composition of positive and negative HOM clusters measured with atmospheric pressure interface time-of-flight mass spectrometers at three different temperatures (25, 5, and − 25) ∘ C).
Journal ArticleDOI
Denuder/filter sampling of organic acids and organosulfates at urban and boreal forest sites: Gas/particle distribution and possible sampling artifacts
TL;DR: In this paper, a comparison of side-by-side sampling systems, a high volume sampler (HVS) and a low volume (LVS) denuder/filter sampling system allowing for separate collection of gas- and particle-phase organics was made.
Journal Article
Patterns in airborne pollen and other primary biological aerosol particles (PBAP), and their contribution to aerosol mass and number in a boreal forest

TL;DR: In this paper, Manninen et al. presented a list of departments and departments of the University of Helsinki and the Max Planck Institute for Chemistry, respectively, with their corresponding departments of biology and chemistry.
Journal ArticleDOI

TL;DR: In this paper, the authors studied new particle formation and modal behavior of ultrafine aerosol particles on the high East Antarctic plateau at the Concordia station, Dome C (75°06' S, 123°23' E).
Journal ArticleDOI
