This manuscript presents a significant step forward in presenting a new method to combine extensive satellite data (ice thickness retrievals from radar altimetry in this case) that were accumulated over a long time of one month. As the sea ice can move several hundred kilometers during this time period, averaging data without correcting for drift can significantly blur the results. With the new method, only data that have remained in the same sea ice regime are averaged. The method has received widespread attention, and the audience in the recent ESA Living Planet Symposium mentioned and recognized this work during the public discussion. The community is aware of this work and I am convinced that numerous data providers will implement the method shortly.
