Short summary

Surface O₃ was measured at four sites in the north-eastern interior of South Africa, which revealed that O₃ is a regional problem in continental South Africa, with elevated O₃ levels found at rural background and industrial sites. Increased O₃ concentrations were associated with high CO levels predominantly related to regional biomass burning, while the O₃ production regime was established to be predominantly VOC limited. Increased O₃ is associated with strong seasonality of precursor sources.
