Short summary

High-frequency online measurement of gas- and particle-phase nitro-aromatic compounds (NACs) at a rural site in China, heavily influenced by biomass burning events, enabled the analysis of the production pathway of NACs, including an explanation of strong persistence in the daytime. The contribution of secondary processes was significant, even during the dominant wintertime influence of primary emissions, suggesting the important role of regional secondary chemistry, i.e. photochemical smog.
