Short summary

The HONO concentrations during clean, polluted, and severely polluted days were 1.2, 2.3, and 3.7 ppbv. The contributions of the three sources varied under different pollution levels. The proportion of homogenization gradually increased in the second half of the night due to the steady increase in NO. The values of P_OH+NO^net, C_HONO, and P_unknown in the severely polluted period were comparatively larger than those in other periods, indicating that HONO participated in many reactions.
