Short summary
This paper presents the detailed molecular composition of free tropospheric aerosol. We studied three pollution events with different origins and residence times and observed differences in the molecular composition pertaining to the atmospheric oxidation. The results indicated that the transport pathways contributed to the observed differences and imply that emissions injected into the free troposphere are longer-lived than those in the boundary layer.
