What we would need is two different kinds of graphics:
1. A vertical profile, meaning a timeseries going from August to December (2018 as fairly normal year, 2019 and 2020) with a colour covering the part of the stratosphere where the ozone hole is. Basically, having a profile over time until December. Colours need to be advised. Vincent-Henri said, we would need to discuss, whether to take the south pole or take a certain zone like 80 degree to pole average or even 70° to pole, to make things smoother, but happy on your advise on this.
* This would be also good to have for 2020 over the Arctic (in comparison with a "normal" year too)
2. A set of three maps. 2018, 2019 and 2020 over the Antarctic with the maximum extent of the ozone hole for each year. Like a mini version of what you already did for all the year since 1979. But of course in high resolution.
* Again the same for the arctic would be great.
