Abstract Chemical transport model (CTM) simulation of organic aerosol (OA) is
always challenged by numerous sources and complicated formation processes of
secondary organic aerosol. In this study, we conducted a source-specific, wholeyear (2011) simulation of organic aerosol in Europe using the air quality model
CAMx v6.3 with volatility basis set (VBS) scheme after implementing new findings from experimental studies. The VBS module was parameterized based on
the latest data for gasoline and diesel vehicles and wood combustion from the
smog-chamber experiments. The model performance was evaluated using OA measurements from the ACSM (Aerodyne Chemical Speciation Monitor) and AMS
(Aerodyne Aerosol Mass Spectrometer) network and contributions from 6 different anthropogenic (gasoline and diesel vehicles with old or new technologies,
biomass burning, and other sources (OP)) and biogenic sources were estimated. The
