The top panels (a, b) show all the members of our multi-model ensemble, and the bottom panels (c, d) the minimum over that ensemble. The left panels (a, c) show the total ozone column, the right panels (b, d) the stratospheric column alone. For the period 1950–2014 we have plotted the historical simulations; for the period 2014–2100, the SSP5-8.5 simulations. The model names are given in the legend, followed by the corresponding number of simulations shown for the historical and SSP5-8.5 portions, respectively, in parentheses. The solid grey and dashed black lines show the NIWA-BS27 and MERRA228 reanalyses, respectively. All ozone columns are here averaged over the Arctic, defined as the region 60∘−90∘N.
