The particulate matter (PM) mass concentration in cities corresponds to the sum of the concentrations measured at the background stations and the difference between the city and background stations. For this reason, at high background concentrations of PM, the result of emission reduction measures is low. Most of the reported episodes of increased PM concentrations in winter in central European cities are caused by sources of local or regional origin from the combustion of coal and / or biomass for heating purposes. Improvement of air quality in cities is possible provided that causality is understood, especially when it comes to atmospheric aerosol and its concentration, sources and origin.\nThe aim of the work was to determine the origin of air pollution in Prague on the basis of one year parallel measurements of atmospheric aerosol at two urban background stations.\n\n

Air Pollution Origin Based on One-year PM2.5 and PM10 Measurement at Two Suburban Sites in Prague.

The objective of this study was to determine air pollution origin in Prague based on the chemical composition of 24h atmospheric aerosol (AA) samples collected in parallel for one-year at two suburban sites. Chemical analysis of PM2.5 and PM10 for elements by ICP-MS, for elemental and organic carbon by thermo-optical method and water-soluble inorganic ions by IC was performed. The AA in Prague air shed was well mixed and nine common PM10 sources of local, urban, regional and long range transport (LRT) origin were apportioned.

Creation of wind rosettes using the CALMET model
Škáchová, H. ; Vlček, O. ; Trusina, Jan
The CALMETT model is a part of dispersion modeling system (CALPUFF), which is a diagnostical modul for flow fields that counts vertically divided fields of wind direction and wind speed. The model is able to calculate micrometeorological characteristics of the boundary layer above the Earth´s and water surface. To verify the model, test calculations were made at two professional stations CHMI (Praha – Libuš, Mošnov) for the period of 2008 – 2012. Košetice Observatory was chosen for comparison of the stability divided and total height rosettes. The results showed that the CALMETT model is a suitable tool for creating stability divided wind rosettes. When calculating wind rosettes, the correct settings and representativeness of input data should be born in mind.
