The concentrations and particle-size distribution of sugars in Arctic aerosol samples were studied to investigate their potential sources and transport. Sugars are constituents of the water-soluble organic compounds (WSOC) fraction in aerosol particles where some saccharides are used as tracers of Primary Biological Aerosol Particles (PBAPs). Monosaccharides (arabinose, fructose, galactose, glucose, mannose, ribose, xylose), disaccharides (sucrose, lactose, maltose, lactulose), alcohol-sugars (erythritol, mannitol, ribitol, sorbitol, xylitol, maltitol, galactitol) and anhydrosugars (levoglucosan, mannosan and galactosan) were quantified in aerosol samples collected during three different sampling campaigns (spring and summer 2013, spring 2014 and 2015). The mean total concentrations of sugars were 0.4 ± 0.3, 0.6 ± 0.5 and 0.5 ± 0.6 ng m-3 for 2013, 2014 and 2015 spring campaigns, while the mean concentration increased to 3 ± 3 ng m-3 in the summer of 2013. This work identified a reproducibility in the sugars trend during spring, while the summer data in 2013 allowed to us to demonstrate strong local inputs when the ground was free of snow and ice. Furthermore, the study aims to show that the two specific ratios of sorbitol & galactiol to arabinose were diagnostic for the type of biomass that was burnt. This study demonstrates that not only is long-range atmospheric transport significant. But depending on seasonality, local inputs can also play an important role in the chemical composition of sugars in Arctic aerosol.
