dc.description.abstract Atmospheric aerosols have been measured in Finnish Lapland from January 1992 to June 1994. A seasonal cycle in particle number concentration, measured using a condensation particle counter, is observed. Aerosol samples have been collected by a virtual impactor (VI) in two size ranges. The filters have been changed every 48 hours. Most fine particle samples are acidic: 91% of the measured anions (neq/m3) to measured cations (neq/m3) ratios are above one. According to a trajectory statistical analysis, high sulphate concentrations come to Finnish Lapland from all of continental Europe. The source areas of the highest observed ammonium concentrations are in Western Europe.
