Circumarctic seasonal measurements of permafrost parameters (thaw depth, snow depth, vegetation and tree height, water level and soil properties)

The Permafrost Thaw Action Group is committed to the standardized field data collection necessary to quantify permafrost thaw dynamics across circumarctic regions. 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.

永久冻土融化行动组致力于实现标准化现场数据收集，以量化环北极地区永久冻土融化动态。该努力始于2021年，作为陆地多学科分布式观测站研究北极联系（T-MOSAiC）项目的一部分。免费应用程序myThaw在促进数据收集方面发挥了关键作用，使用户能够输入并上传测量数据和照片。该应用程序支持收集与各种永久冻土融化相关参数的标准化测量，包括季节性融化深度、积雪深度、植被高度、水位、土壤特性以及多个环北极地点的树木高度。每个数据集都附有详细的元数据，包含数据收集时间、地理坐标以及地表特征，如植被、地表和水面特征等信息。
