Thermal State of Permafrost in North America - continuously observed ground temperatures, 2021-2022

This work coordinates data collection using standard equipment and protocols at North American and Russian sites. These data sets provide the baseline to assess the future rates of change in near-surface permafrost temperatures and permafrost boundaries, and to provide spatial data for validation of climate scenario models and temperature reanalysis approaches. The work represents the United States (US) contribution to the ongoing activities of the Global Terrestrial Network for Permafrost that obtains temperatures in a large number of globally distributed monitoring sites in order to provide a snapshot of permafrost temperatures in both time and space. The US National Science Foundation (NSF) funded this work with award #0520578, #0632400, #0856864, and #1304271.

本研究统筹依托标准设备与规程，在北美及俄罗斯境内的多个站点开展数据采集工作。本数据集可为评估近地表多年冻土温度与多年冻土边界的未来变化速率提供基准参照，同时可为气候情景模型及温度再分析方法的验证提供空间数据支持。本研究代表美国（United States, US）对全球多年冻土陆地监测网络（Global Terrestrial Network for Permafrost）现有运行活动的贡献：该网络在全球广泛分布的监测站点采集温度数据，以期获取时间与空间双维度下的多年冻土温度分布快照。本研究由美国国家科学基金会（National Science Foundation, NSF）通过编号为#0520578、#0632400、#0856864及#1304271的项目资助。
