Short summary
We studied how ozone in the upper atmosphere above the Arctic changed during winter 2019/2020 using ground-based microwave measurements from Kiruna, Sweden and compared them with satellite observations. The results matched closely and showed unusually strong decrease in ozone, peaking in early April. We used air mass tracking methods to estimate how much chemically induced ozone was lost over the season. This shows ground measurements can reliably monitor changes and support satellites.
