Size-segregated aerosol particles were collected during winter sampling campaigns at a coastal (55 degrees 37' N, 21 degrees 03'E) and an urban (54 degrees 64' N, 25 degrees 18' E) site. Organic compounds were thermally desorbed from the samples at different temperature steps ranging from 100 degrees C to 350 degrees C. The organic matter (OM) desorbed at each temperature step is analysed for stable carbon isotopes using an isotope ratio mass spectrometer (IRMS) and for individual organic compounds using a Proton Transfer Reaction Time-of-Flight Mass Spectrometer (PTR-MS). The OM desorbed at temperatures
