The 1980–2015 September–October averaged influence of iodine chemistry on the Antarctic stratospheric ozone depletion: (A) percentage impact over the stratospheric vertical column; (B) effect at 16-km altitude (∼100 hPa); and (C) averaged meridional slice at 0° longitude, in which the effect of iodine chemistry can be seen spatially as a function of latitude and altitude. The relative percentage difference has been computed as ((iodine run – no iodine run)/no iodine run) × 100.
