Maximum regional ozone enhancement in September occurs between 10º - 20ºS over Zambia and Zimbabwe, which is designated as the core of the ‘photochemical reactor’. Features that contribute towards the ‘giant natural photochemical reactor’ are abundant sources of ozone precursors (biomass burning, lightning, biogenic and urban-industrial sources), and meteorological conditions that promote anticyclonic recirculation on a subhemispheric scale.enSouthern AfricaTropospheric ozone dataEmissions inventoryBiomass burningAir pollutionConference PresentationDiab, R., Naidoo, M., Zunckel, M., & Carter, W.
