| Zusammenfassung |
| Organic aerosols (OA) represent one of the major constituents of submicron
particulate matter (PM1) and comprise a huge variety of compounds
emitted by different sources. Three intensive measurement field campaigns to
investigate the aerosol chemical composition all over Europe were carried
out within the framework of the European Integrated Project on Aerosol Cloud Climate
and Air Quality Interactions (EUCAARI) and the intensive campaigns of
European Monitoring and Evaluation Programme (EMEP)
during 2008 (May–June and September–October) and 2009 (February–March). In
this paper we focus on the identification of the main organic aerosol
sources and we define a standardized methodology to perform source
apportionment using positive matrix factorization (PMF) with the multilinear
engine (ME-2) on Aerodyne aerosol mass spectrometer (AMS) data. Our source
apportionment procedure is tested and applied on 25 data sets accounting for
two urban, several rural and remote and two high altitude sites; therefore
it is likely suitable for the treatment of AMS-related ambient data sets. For
most of the sites, four organic components are retrieved, improving
significantly previous source apportionment results where only a separation
in primary and secondary OA sources was possible. Generally, our solutions include two
primary OA sources, i.e. hydrocarbon-like OA (HOA) and biomass burning OA
(BBOA) and two secondary OA components, i.e. semi-volatile oxygenated OA
(SV-OOA) and low-volatility oxygenated OA (LV-OOA). For specific sites
cooking-related (COA) and marine-related sources (MSA) are also separated.
Finally, our work provides a large overview of organic aerosol sources in
Europe and an interesting set of highly time resolved data for modeling
purposes. |
