Short summary

We used the WRF-CHEM model to simulate wintertime secondary organic aerosol (SOA) concentrations over Beijing–Tianjin–Hebei (BTH), China. Heterogeneous HONO sources increased the near-surface SOA by 46.3 % in BTH. Direct emissions of glyoxal and methylglyoxal from residential sources contributed 25.5 % to the total SOA mass. Our study highlights the importance of heterogeneous HONO sources and primary residential emissions of glyoxal and methylglyoxal to SOA formation in winter over BTH.
