Short summary
Using year-long aerosol mass spectrometer measurements, roles of secondary organic aerosols (SOA) during haze formations in an urban area of southern China were systematically analyzed. Almost all severe haze events were accompanied by continuous daytime and nighttime SOA formations, whereas coordinated gas-phase photochemistry and aqueous-phase reactions likely played significant roles in quick daytime SOA formations, and nitrate radicals played significant roles in nighttime SOA formations.
