The sources of organic aerosol derived from 25 AMS datasets across Europe

Organic aerosol constitutes the main portion of submicron particulate matter in the atmosphere. It contains a large diversity of compounds emitted from different sources. Three intensive measurement field campaigns were carried out within the framework of EUCAARI and the intensive campaigns of EMEP during 2008 and 2009 all over Europe to investigate the chemical composition of atmospheric aerosol. This paper focuses on the identification of the major sources of organic aerosol and on defining 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.
