Short summary
The observed ratio of organic carbon to element carbon has increased remarkably in Beijing. Here, based on the measurements and model simulation, we show that the enhanced atmospheric oxidizing capacity is an important contributor to that increase by facilitating the aging process of organic aerosols (add oxygen). Our results indicate a ubiquitous enhancement of secondary organic aerosol formation over Beijing–Tianjin–Hebei, China, in the context of increasing oxidizing capacity.
