| Summary: | All main aspects of aerosols – chemical composition, physical properties, and processes from their origin to removal from the atmosphere to the snow surface – have been studied at Aboa since December 1997. This paper reviews main results of the the work done and presents some selected new results. The travel time from the ocean proved to be an important factor determining the chloride-to-sodium ratio. The contribution of organics may be significant in the Aitken mode particles. Aerosol formation and growth has been observed during all summer campaigns. An automatic particle counter system was run for more than three years using power form solar cells and wind generators, with breaks mainly due to power production. Wind radar data suggests that intrusions from higher atmospheric levels affect clearly surface concentrations of both particles and trace gases. |
