Abstract

In spring 1995 the chemical composition of the atmospheric aerosol was examined over a time period of two months at Ny-Alesund, Spitsbergen. The measurements were performed daily at two different heigths (40 m and 474 m asl). Integrated aerosol samples have been collected on cellulose filters and were analysed by means of ion chromatography. The obtained results indicate an early spring period with factor 3 enhanced sulfate and seasalt concntrations at 474 m asl followed by a period with diminishing concentration differences. The concentration differences with height are interpreted by considering the local meteorological conditions affecting the vertical exchange. A possible contribution of local aerosol sources will be discussed.
