Soil Temperature Station Data from Permafrost Regions of Russia (Selection of Five Stations), 1915 - 2000, Version 1

This data set includes soil temperature data from boreholes located at five stations in Russia: Yakutsk, Verkhoyansk, Pokrovsk, Isit', and Churapcha. The data have been compiled into five Microsoft Excel files, one for each station. Air temperature measured at these five stations was also included when available.

This data set was compiled to go with a classroom learning activity called \"How Permanent is Permafrost.\" To view the activity, see the PDF file of the same name under the General Resources section below.

There are two different versions of the Excel files: a complete version and a subsetted version. Both versions exist for each of the five stations for a total of 10 files. The complete versions of the files contain borehole temperature data at all available standard depths: 0.2 m, 0.4 m, 0.6 m, 0.8 m, 1.2 m, 1.6 m, 2.0 m, 2.4 m, and 3.2 m. The subsetted versions of the files contain data from the 0.8 m and 3.2 m depths only. The complete version is more applicable to scientific investigation. The subset version is provided for K-12 teachers and is featured in the \"How Permanent is Permafrost?\" classroom activity.

本数据集包含俄罗斯雅库茨克（Yakutsk）、维尔霍扬斯克（Verkhoyansk）、波克罗夫斯克（Pokrovsk）、伊西特（Isit'）和丘拉普恰（Churapcha）5个监测站的钻孔土壤温度数据。相关数据已整理为5个微软Excel（Microsoft Excel）文件，每个监测站对应一个文件。若有可用实测记录，还将包含上述5个监测站的气温数据。

本数据集配套名为《永久冻土的持久性如何》的课堂学习活动编制。如需查看该活动，请参阅下文“通用资源”板块下的同名PDF文件。

Excel文件共包含两种版本：完整版本与精简版本。5个监测站均分别对应这两种版本，总计10个文件。完整版本涵盖所有可用标准深度的钻孔温度数据，具体为0.2 m、0.4 m、0.6 m、0.8 m、1.2 m、1.6 m、2.0 m、2.4 m及3.2 m。精简版本仅保留0.8 m与3.2 m深度的观测数据。完整版本更适用于科学研究，而精简版本专为K-12阶段教师设计，且为“永久冻土的持久性如何”课堂活动的指定配套数据。
