      abstract     = {We present a comprehensive field campaign conducted in
                      Beijing, September 2016, to elucidate the photochemical smog
                      pollution, i.e. Ozone (O3). The observed daily maximum
                      hydroxyl radical (OH) and hydroperoxy radical (HO2)
                      concentrations were up to 1 × 107 cm-3 and
                      6 × 108 cm-3, respectively, indicating the active
                      photochemistry in autumn Beijing. Photolysis of nitrous acid
                      (HONO) and O3 contributed 1-2 ppbv h-1 to OH primary
                      production during daytime. OH termination were dominated by
                      the reaction with nitric oxide (NO) and nitrogen dioxide
                      (NO2), which were in general larger than primary production
                      rates, indicating other primary radical sources maybe
                      important. The measurement of radicals facilitates the
                      direct determination of local ozone production rate P (Ox)
                      (Ox = O3 + NO2). The integrated P(Ox) reached 75
                      ppbv in afternoon (for 4 h) when planetary boundary layer
                      was well developed. At the same time period, the observed
                      total oxidant concentrations Ox, increased significantly by
                      70 ppbv. In addition, the Ox measurement showed compact
                      increase in 12 stations both temporally and spatially in
                      Beijing, indicating that active photochemical production
                      happened homogenously throughout the city. The
                      back-trajectory analysis showed that Beijing was isolated
                      from the other cities during the episode, which further
                      proved that the fast ozone pollution was contributed by
                      local photochemical production rather than regional
                      advection.},
