“…During the whole sampling period, higher concentrations of levoglucosan were 214 found in the samples under the effect of continental air masses based on five-day backward 215 trajectories ( Fig. S2-S6), consistent with our previous report about lipids, PAHs and 216 phthalates (Kang et al, 2017). Mannosan and galactosan, isomers of levoglucosan, are 217 produced by pyrolysis of cellulose and hemicellulose and can also act as biomass burning 218 tracers (Simoneit, 2002;Fabbri et al, 2009).…”

Terrestrial air masses also bring plentiful organic matter derived from natural and/or anthropogenic activities to the oceanic atmosphere via longrange atmospheric transport (Zhou et al, 1990;Kumar et al, 2012;Hawkins et al, 2010;Srinivas et al, 2011;Kang et al, 2017).

Abstract. Molecular composition and abundance of sugars and secondary organic aerosols (SOA) from biogenic sources over the East China Sea were investigated based on gas chromatography–mass spectrometry. Biogenic SOA tracers and sugars exhibit higher levels in the samples affected by continental air masses, demonstrating the terrestrial outflows of organic matter to the East China Sea. Glucose was the dominant sugar species (0.31–209, 18.8 ng m−3), followed by mannitol – a fungal spore tracer. All sugar compounds show generally higher average concentrations in the nighttime than in the daytime. 3-Methyl-1,2,3-butanetricarboxylic acid, one higher generation photooxidation tracer of monoterpene SOA, was found to be the most abundant species among measured biogenic SOA markers, suggesting the input of aged organic aerosols through long-range transport. Fungal-spore-derived organic carbon (OC) was the biggest contributor to total OC (0.03 %–19.8 %, 3.1 %), followed by sesquiterpene-derived secondary OC (SOC), biomass-burning-derived OC, and monoterpene- and isoprene-derived SOC. Larger carbon percentages of biogenic primary OCs and SOCs in total OC presented in the terrestrially influenced aerosols indicate significant contributions of continental aerosols through long-range transport. Positive matrix factorization results illustrate that the secondary nitrate and biogenic SOA, biomass burning, and fungal spores were the main sources of OC in marine aerosols over the East China Sea, again highlighting the importance of the Asian continent as a natural emitter of biogenic organic aerosols together with anthropogenic aerosols over the coastal marine atmosphere.
