This study assesses the variability of organic aerosol (OA) sources monitored at the rural background site Frýdlant. Non-refractory PM1 was evaluated in two seasons of\n2021. The positive matrix factorization with the multi-linear engine was used to determine the sources of OA at Frýdlant site, with four factors resolved both in winter and\nsummer.

Ambient Organic Aerosol Origin at Rural Background Site in the Czech Republic.
Lhotka, Radek
Atmospheric aerosol (AA) are ubiquitous particles in the atmosphere that influence Earth’s climatic system, environmental interactions,\nand human health. AA is emitted directly from primary sources or formed in the atmosphere via the oxidation of gas-phase precursors\nwith subsequent partitioning resulting in low-volatility products into the particle phase. Among AA, great interest is dedicated to organic\naerosol (OA) since it can represent from 20 to 90% of the total submicron mass.

To improve the air quality the underlying causalities must be well understood,particularly when it comes to aspects such as PM concentration, sources and their origin. The aim of this work was to determine air pollution origin at NAOK based on atmospheric aerosol (AA) data of different time resolution measured during intensive summer campaing.
