A particle nucleation and growth event following isoprene photooxidation (initial mixing ratio 350 ppbv) has been analyzed using a novel inverse modeling procedure. Diameter growth rates were found to reach 100 nm h–1, while the nucleation rate was relatively low, around 1 cm–3 s–1. These empirical rates were determined based on the measured aerosol size distributions, independent of classical nucleation theory. Continuous evaporation after the lights were turned off indicates that 10 pptv is a lower limit of the effective saturation vapor pressure of its condensable oxidation products. The aerosol yield was 0.8%, in agreement with other studies.
