Time Series of Seasonally Frozen Ground Depth in the Russian Arctic, 1930-1990

This data set consists of seasonally frozen ground depth measurements based on soil temperatures in the Russian Arctic. Seasonal freezing and thawing processes in cold regions play a major role in ecosystem diversity, productivity, and the Arctic hydrological system. Long-term changes in seasonal freeze and thaw depths are also important indicators of climate change. Investigators collected data from 211 ground-based stations. The record extends from 1930 to 1990 and includes seasonal freeze depths derived from soil temperature data that are averaged yearly. Data are in tab-delimited ASCII text format.

本数据集包含基于俄罗斯北极地区土壤温度测算得到的季节冻土深度实测数据。寒冷地区的季节性冻融过程对生态系统多样性、生产力水平以及北极水文系统具有关键作用。季节性冻融深度的长期变化亦是气候变化的重要指示指标。研究人员从211个地面观测站采集了本数据集的相关数据，数据记录的时间跨度为1930年至1990年，包含基于逐年平均土壤温度数据推导得到的季节冻结深度数据。数据采用制表符分隔的ASCII文本格式存储。
