This effort began in 2021 as part of the Terrestrial Multidisciplinary distributed Observatories for the Study of the Arctic Connections (T-MOSAiC). The free myThaw app has been instrumental in facilitating data collection, allowing users to enter and upload measurement data and photos. The app supports the collection of standardized measurements for various permafrost thaw-related parameters, including seasonal thaw depth, snow depth, vegetation height, water level, soil properties, and tree height across multiple circumarctic sites. Each dataset is accompanied by detailed metadata containing information on the timing of data collection, geographical coordinates, and land surface characteristics, such as vegetation, ground surface, and water features. These data sets adhere to the multiparameter protocol for standardized monitoring as outlined by Boike et al.
