Minimum total column ozone in September to October predicted by various models, plus observations from the National Institute of Water and Atmosphere Research (NIWA) total ozone database in New Zealand (Bodeker et al., 2005<ref name="Bodeker et al, 2005">Bodeker, G.E., Shiona, H. and Eskes, H. 2005. Indicators of Antarctic ozone depletion, ''Atmos. Chem. Phys.'', '''5''', 2603-2615.</ref>). Solid and dashed curves show smoothed values. Light gray shading shows when CFCs and halons are expected to return to 1980 values. Adapted from WMO (2007<ref name="WMO, 2007">WMO, 2007.
