An analysis of in situ measurements of ultrafine volatile aerosols in the plume near field of the DLR aircraft ATTAS using low (0.02 g/kg) and high (2.7g/kg) fuel sulfur contents (FSCs) is presented. The observed growth of nanoparticles (diameter 5–10 nm) is reproduced in detail by a microphysical simulation with chemi‐ion emissions of 2.6×10 17 /kg fuel. Volatile aerosol dynamics is controlled by sulfuric acid (H 2 SO 4 ) for high FSC, consistent with a S to H 2 SO 4 conversion of 1.8%. The very high conversion for low FSC (55%) prescribed in the model to match the observations contradicts direct in situ measurements of H 2 SO 4 and suggests that species other than H 2 SO 4 , likely exhaust hydrocarbons, control particle growth in such cases.
