Extended Data Fig. 1: Time series, from 1960 to 2100, of total column ozone (TCO, DU), averaged from 90°S-90°N, from the simulations analysed in this study.
From: Integrated ozone depletion as a metric for ozone recovery
Part a) plots annual mean model data and b) plots the data after it has been smoothed using an 11-point boxcar smoothing, following Dhomse et al34. The large difference at 2100 between Base and the scenario with 30-year emissions of CFC-11 and CFC-12 arises from the large increase in (and subsequent emission from) their banks, assumed in that scenario (as discussed in Keeble et al.25).
