Organic aerosol (OA) is a key component of total submicron particulate matter (PM1), and comprehensive knowledge OA sources across Europe crucial to mitigate PM1 levels. has well-established air quality research infrastructure from which yearlong datasets using 21 chemical speciation monitors (ACSMs) 1 mass spectrometer (AMS) were gathered during 2013-2019. It includes 9 non-urban 13 urban sites. This study developed state-of-the-art source apportionment protocol analyse long-term spectrum data by applying the most advanced strategies (i.e., rolling PMF, ME-2, bootstrap). harmonised was followed strictly for all 22 datasets, making results more comparable. In addition, it enables quantification common components such as hydrocarbon-like (HOA), biomass burning (BBOA), cooking-like (COA), oxidised-oxygenated (MO-OOA), less (LO-OOA). Other coal combustion (CCOA), solid fuel (SFOA: mainly mixture peat combustion), cigarette smoke (CSOA), sea salt (mostly inorganic but part spectrum), coffee OA, ship industry could also be separated at few specific Oxygenated (OOA) make up (average = 71.1%, range 43.7 100%). Solid combustion-related BBOA, CCOA, SFOA) are still considerable with in 16.0% yearly contribution yet winter months (21.4%). Overall, this works effectively sites governed different generates robust consistent results. Our work presents overview unique combination high time resolution (30-240 min) coverage (9-36 months), providing essential information improve/validate quality, health impact, climate models.
