Highly Time-Resolved Elemental Source Apportionment at a Prague Urban Traffic Site
Original language description
Positive Matrix Factorization was used for source apportionment of 2-hour online metals (Xact625i, PM2.5) and elemental and organic carbon (EC/OC analyser, PM1) data at an urban traffic site in Prague, Czech Republic, for two month-long periods in spring (February – March) and winter (November – December), 2020 (400 samples). Five factors were obtained for spring: Local heating (39%), Soil/road dust (21%), Secondary inorganic aerosol (20%), Traffic (12%), and Road salt (9%), while four factors were resolved for winter: Local heating (20%), Soil/road dust (31%), Secondary inorganic aerosol (SIA, 36%), and Traffic (13%). Aside from SIA, the sources were of local origins. Air mass back trajectories calculated by HYSPLIT and concentration weighted trajectories (CWT) were used to identify long-distance sources. Greater PM concentrations during winter (~3 times greater) wereattributed to both lower boundary layer heights and more abundant air masses from Central Europe, compared to more marine air masses during spring.
