Abstract

Temporal and spatial variations of the atmospheric sulphur dioxide and particle sulphate concentrations have been analysed for the Alpine Carpathian region, using observations of 30 EMEP stations in the 1977-1991 period. After describing the data base used and the applied statistical methods, annual variations of the two contaminants is presented. Long-term tendencies, expressed in five-year means, are further analysed with bimonthly resolution of the annual variation. These variations are displayed for three lowland-based and three mountainous stations, with the most complete sets of data. Finally, the dependence of the concentrations on latitude, longitude and altitude is analysed, using all available stations and five-year averages in the above bimonthly separation.
