The authors note that they included monthly atmospheric methane concentrations maps, starting in May 2020 and terminating in May 2021. However, the satellite devices measuring concentrations of atmospheric methane do not operate at such high latitudes during the winter months. The maps for the period November 2020–February 2021, presented on Fig. 1, repeat the signal from October 2021. Thus they should not be taken into consideration. The authors thank Ilse Aben (Netherlands Institute for Space Research) and Benjamin Poulter (National Aeronautics and Space Administration) for pointing out this issue. This does not affect the results or conclusions of the article. The corrected Fig. 1 and its legend appear below. The online version has been corrected. (Figure Presented).
