Seasonal and diurnal variation in the size distribution of fine carbonaceous particles over rural Hungary

Size distribution of fine atmospheric aerosol was measured at K-puszta, Hungary during summer and winter of 2000 and spring and autumn of 2001. The sampling was carried out by an electrical low pressure impactor which fractionated fine particles (d<1.7 μm) in eight size ranges. In this paper diurnal and seasonal variations of the concentration and size distribution of fine sulfate, total carbon (TC) and water soluble organic compounds (WSOC) are presented. The results indicate that the concentrations of sulfate, TC and WSOC are different in different seasons. Potential sources of these variations are briefly discussed.
