Short summary
Over 2 years of atmospheric aerosol organic functional group and microphysics measurements at the world's northernmost land observatory offer a unique high-latitude dataset. Lower organic mass (OM) concentrations and higher OM fractions accompany smaller particles during summer, with opposite results during winter to spring. Seasonally, the OM oxidation level is highest in winter, associated with primary marine alcohol groups. In summer, secondary processes dominate the marine influence on OM.
