AB: Aerosol particles in a given environment are largely influenced by surrounding regions which can act as either direct sources or via the production of species which become incorporated into pre-existing particles. Presented here are the major characteristics, including chemical composition, of ambient aerosols measured by an Aerosol Time-of-Flight Mass Spectrometer (ATOFMS) and other instruments 200 km above the Arctic Circle. Abisko Scientific Research Station, operated by the Royal Swedish Academy of Sciences, is subject to airmasses with several different origins. By comparison of wind trajectories, the influence of the sea, boreal forest, and industrial regions surrounding Abisko are evident in the measured spectra. These aerosol particles are of further interest due to the climate changes occurring in the polar region. Also important to this study is the simultaneous occurrence of an International Polar Year, an intensive research period focusing on the environments of both polar areas.
