Short summary
This work helps to better understand the potential climate and health impacts of airborne aerosol particles. We applied a new technique to provide a diagnostic fingerprint of the organic compounds present in aerosols. We followed changes in this fingerprint over time in lab experiments which mimic the conversion of plant emissions into aerosols. Our results compare well with computer simulations of the reactions and we conclude that the technique merits continuing use and development in future.
