Short summary
We investigated NOx impacts on the formation of secondary organic aerosol (SOA) mass from b-pinene and we could reveal two different mechanisms of impacts. One of them was the impact of NOx on OH that could explain increasing SOA yield with increasing NOx at low NOx conditions. The other was the suppression of new particle formation limiting the condensational sink for the SOA precursors. This effect could explain a substantial fraction of the decrease of SOA yield observed at high NOx.
