Short summary
The secondary organic aerosol (SOA) produced by the photooxidation of isoprene with and without inorganic seed is simulated using the Unified Partitioning Aerosol Phase Reaction (UNIPAR) model, assuming a single homogenously mixed organic–inorganic phase. UNIPAR is used to determine the sensitivity of isoprene SOA formation to NOx, aerosol acidity and aerosol liquid water content. Isoprene SOA is found to be most sensitive to aerosol acidity but dynamically related to all three parameters.
