Participating stations
Since the beginning of the project field measurements in the summer of 2021 the following stations participated in the data collection process via myThaw app on a regular basis.
Those sites are based in permafrost regions in the northern hemisphere. The visualisation of Data is supported by The Artic Permafrost Geospatial Centre (APGC).
