Short summary
This study revealed the driving role of nitrate in urban haze development in the North China Plain (NCP) during summertime. Several factors favoring the rapid nitrate formation were investigated in detail. The higher concentration and, in particular, the higher contribution of nitrate in PM1 suggest an urgent need to initiate ammonia emission control measures and further reduce NOx emissions over the NCP region.
