Short summary

Our study highlights the importance of molecular composition in constraining the chemical properties of cooking SOA as well as understanding the contribution of aldehydes in formation of SOA from cooking emissions. We show that fragmentation reactions are key in atmospheric processing of cooking SOA, and aldehydes emitted from cooking emissions contribute substantially to SOA formation. Our study provides a framework to better predict SOA formation in and downwind of urban atmospheres.
