Short summary
We study primary emissions and secondary aerosol (SA) from an aircraft turbofan. By monitoring the chemical composition of both gaseous and particulate emissions at different engine loads, we explained SA formed in an oxidation flow reactor (PAM) by the oxidation of gaseous species. At idle, more than 90 % of the secondary particle mass was organic and could be explained by the oxidation of gaseous aromatic species, while at an approximated cruise load sulfates comprised 85 % of the total SA.
