Short summary

The abundance, potential precursors, and main formation mechanisms of nitrogen-containing organic compounds (NOCs) in PM_2.5 during winter were compared among cities with different energy consumption patterns. The aerosol NOC pollution during winter in China is closely associated with the intensity of precursor emissions and the aqueous-phase processes. Our results highlight the importance of emission reduction strategies in controlling aerosol NOCs pollution during winter in China.
