Short summary
The Antarctic ozone hole remains a critical global challenge. Accurately measuring the gases that cause it during twilights is difficult due to rapid chemical changes. We used advanced computer simulations to reproduce observations at 2 Antarctic stations to account for these fluctuations and the Earth's curvature. Our results improve the accuracy of atmospheric monitoring, helping scientists better track the recovery of the ozone layer and understand the complex chemistry driving its depletion.
