Short summary
This work explores the impact of acidic sulfate aerosol on the formation of SOA from isoprene and 1,3-butadiene. This study expands on previous work by extending the analysis over a broader range of humidities and aerosol liquid water contents. Extending the experiments to a wider range of hydrocarbons and across a more realistic range of humidities provides data of greater atmospheric relevance and contributes to development of acidity-influenced SOA chemistry mechanisms in air quality models.
