Short summary

This model study is about the effect of black carbon (BC) and the boundary layer interactions on surface ozone in an area of severe haze and ozone pollution in China. It shows the following: BC not only reduces photolysis rate, but also suppresses boundary layer (BL) development, then confines more ozone precursors. The BL suppression leads to less ozone aloft being entrained downward and finally leading to surface ozone reduction before noon.
