TL;DR: In this article, a comprehensive field campaign was carried out in summer 2014 in Wangdu, located in the North China Plain, where a month of continuous OH, HO2 and RO2 measurements was achieved.

TL;DR: The relative incremental reactivity (RIR) results demonstrate that anthropogenic VOCs reduction is the most efficient way to mitigate ozone pollution at all sites, of which alkenes dominate >50% of the ozone production.

TL;DR: In this article, the first wintertime in situ measurements of hydroxyl (OH), hydroperoxy ( HO2 ) and organic peroxy( RO2 ) radicals were presented. But, they largely underestimated HO2 and RO2 concentrations by factors up to 5 during pollution episodes, indicating a deficit in understanding of the gas phase chemistry in the high NOx regime.

TL;DR: In this paper, the authors measured N2O5 in the surface layer taken at an urban site in Beijing, and found that the nocturnal pNO3-formation potential by N2 O5 heterogeneous uptake was calculated to be 24-85 μg m −3 per night and on average 57 μg m -3 per day during days with pollution.

TL;DR: In this article, in situ measurements of ROx radical precursors and products were carried out in four Chinese megacities (Beijing, Shanghai, Guangzhou, and Chongqing) during photochemically polluted seasons.
