Short summary

The Yangtze River Delta is one of the most densely populated regions in China with severe air quality issues that have not been fully understood. In this study, we found that severe photochemical and haze pollution occurred. Strong local photochemistry was elucidated to favor the O₃ production under a VOC-limited regime, whereas it moved towards a VOC-NO_x limited regime in summer. This study emphasizes that cross-regional control measures are crucial to improve air quality in the YRD region.
