This led to five clusters strongly controlled by natural emissions (eBC 8–15 ng/m3) and three anthropogenic clusters with larger particle concentrations in the accumulation mode (eBC 29–77 ng/m3). The HGF and CCN properties of the eight aerosol clusters differ drastically. Anthropogenic clusters feature high growth factors (1.62–1.81) and low CCN κ values (0.10–0.46), while natural clusters show lower HGF (1.38–1.70) but remarkably higher κ values (0.35–0.51). Extrapolating the CCN properties on the basis of the cluster analysis to annual timescales suggests that biogenic organic aerosol may drive Arctic aerosol production during summer This study was founded by the Danish Environmental Protection Agency (MIKA/DANCEA funds for Environmental Support to the Arctic Region) and “Arctic Monitoring and Assessment Program” (AMAP), the Danish research project “Short lived Climate Forcers” (SLCF), and the Danish Council for Independent Research (Project NUMEN, DFF‐FTP‐4005‐00485B), the Nordic Centre of Excellence (NCoE) Cryosphere‐Atmosphere Interactions in a Changing Arctic Climate (CRAICC), and the Villum Foundation.
