Thermal State of Permafrost in North America - annually observed ground temperatures, 2017

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 funded this work with award #0520578, #0632400, #0856864, and #1304271.

本研究采用标准设备与实验规程，在北美及俄罗斯境内的多个站点统筹开展数据采集工作。本数据集可为评估近地表冻土温度与冻土边界的未来变化速率提供基准基线，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撑。本研究是美国（United States, US）对全球冻土陆地网络（Global Terrestrial Network for Permafrost）持续工作的贡献组成部分；该网络通过全球范围内大量分布式监测站点获取温度数据，旨在从时间与空间维度全面呈现冻土温度的整体分布概况。本研究由美国国家科学基金会（US National Science Foundation）通过资助编号#0520578、#0632400、#0856864及#1304271资助完成。
