Short summary
This work addresses unclear roles of heterogeneous N2O5 reactions and chlorine activation processes in the polluted residual layer from a mountaintop measurement in northern China. The results revealed efficient ClNO2 production in the coal-fired plumes in this region, having large impacts on next-morning photochemistry. Fast heterogeneous N2O5 reactions dominate the nocturnal NOx loss and contribute to substantial nitrate formation, which may boost the haze pollution in northern China.
