We use an ultrahigh-resolution 15 Tesla Fourier transform ion cyclotron resonance mass spectrometer (15T FT-ICR MS) to elucidate the compositional changes in Arctic organic aerosols collected at Ny-Ålesund, Svalbard, in May 2015. The FT-ICR MS analysis of airborne organic matter provided information on the molecular compositions of aerosol particles collected during the Arctic spring period. The air mass transport history, combined with satellite-derived geographical information and chlorophyll concentration data, revealed that the molecular compositions of organic aerosols drastically differed depending on the origin of the potential source region. The protein and lignin compound populations contributed more than 70% of the total intensity of assigned molecules when the air masses mainly passed over the ocean region. Interestingly, the intensity of microbe-derived organics (protein and carbohydrate compounds) was positively correlated with the air mass exposure to phytoplankton biomass proxied as ... : Supplement to: Choi, J H; Jang, E; Yoon, Y J; Park, Jae Yeon; Kim, T-W; Becagli, Silvia; Caiazzo, L; Cappelletti, David; Krejci, Radovan; Eleftheriadis, Konstantinos; Park, Ki-Tae; Jang, Kyoung-Soon (2019): Influence of biogenic organics on the chemical composition of Arctic aerosols.
