Short summary

In this study, we determined the particle-size-dependent molecular composition of secondary organic aerosol (SOA) that was produced from β-pinene, an important biogenic precursor. We find that the composition changes significantly with particle size, and these changes can be linked to changes in the chemical processes that contribute to particle growth. Measurements of this type can aid the modeling and prediction of SOA formation.
