Short summary
We present the OH and HO2 radical observations at the Shenzhen site (Pearl River Delta, China) in the autumn of 2018. The diurnal maxima were 4.5 × 106 cm−3 for OH and 4.2 × 108 cm−3 for HO2 (including an estimated interference of 23 %–28 % from RO2 radicals during the daytime). The OH underestimation was identified again, and it was attributable to the missing OH sources. HO2 heterogeneous uptake, ROx sources and sinks, and the atmospheric oxidation capacity were evaluated as well.
