Stratospheric ozone monitoring | 2019-2020

In 2019 the Antarctic ozone hole was exceptionally weak; in 2020 it was exceptionally strong; and an ozone hole appeared above the Arctic.
In order to prove the scientific potential of the ALTIUS measurements, we simulated ALTIUS data and measured how they could constraint a model of the ozone layer.
Community-wide assessment confirms the long-awaited slow rise of ozone in the upper stratosphere. In the lower stratosphere declining ozone levels are still the subject of heated debates.
