Short summary
Accounting for the continuing long-term decrease of pollution ozone and the large 2020 Arctic stratospheric ozone depletion event improves estimates of background ozone changes caused by COVID-19-related emission reductions; they are smaller than reported earlier. Cooperative, international emission control efforts aimed at maximizing the ongoing decrease in hemisphere-wide background ozone may be the most effective approach to improving ozone pollution in northern midlatitude countries.
