Short summary
We present intensive field measurement of ClNO2 in the Pearl River Delta in 2019. Large variation in the level, formation, and atmospheric impacts of ClNO2 was found in different air masses. ClNO2 formation was limited by the particulate chloride (Cl) and aerosol surface area. Our results reveal that Cl originated from various anthropogenic emissions rather than sea sources and show minor contribution to the O3 pollution and photochemistry.
