      abstract     = {The degradation of trace gases and pollutants in the
                      troposphere is dominated by their reaction with hydroxyl
                      radicals (OH). The importance of OH rests on its high
                      reactivity, its ubiquitous photochemical production in the
                      sunlit atmosphere, and most importantly on its regeneration
                      in the oxidation chain of the trace gases. In the current
                      understanding, the recycling of OH proceeds through HO2
                      reacting with NO, thereby forming ozone. A recent field
                      campaign in the Pearl River Delta, China, quantified
                      tropospheric OH and HO2 concentrations and turnover rates by
                      direct measurements. We report that concentrations of OH
                      were three to five times greater than expected, and we
                      propose the existence of a pathway for the regeneration of
                      OH independent of NO, which amplifies the degradation of
                      pollutants without producing ozone.},
