Abstrakt: We analyzed c-ToF-AMS data from a summer (20. 6.–31. 7. 2012) and winter (8. 1.–19. 2. 2013) measurement campaign at a suburban site Prague-Suchdol. The observed chemical composition with dominating organics in both seasons was in accordance with previous measurements at this site.The modal diameter of size distribution occurred at higher values during episodes of increased total concentration and decreased temperature. Furthermore, we compared the AMS data with organic carbon elemental carbon field analyzer (OC/EC) measurement. This comparison together with analysis of particular organic fragments revealed that winter aerosol was less oxidized and more influenced by biomass burning. Such characteristics point to an influence of local domestic heating in winter.
