Soil temperatures along a transect near Thule Air Base, Greenland, 2013

Soil temperatures at approximately 10 cm depth along a 55+ meter long transect near Thule Air Base, Greenland. The transect spans a gradient from wet tundra to polar semi-desert. iButton. IButtons installed in 2013 DOY166, removed DOY222 in 2012. Temperature collected ever four hours. Data processed to remove values when iButtons were not in soil and equalized with soil temperature. .csv, comma-delimited text. Data columns are: plot number, year, day of year, hour of day, minute of hour, fractional day of year, fractional year, temperature in C. Temperature resolution is 0.5 C

本数据集涵盖格陵兰图勒空军基地附近一条长度超55米的样带的约10厘米深度土壤温度数据。该样带的生境梯度覆盖湿苔原至极地半荒漠。本研究采用iButton温度记录仪开展数据采集，记录仪于2013年DOY166布设，于2012年DOY222移除。温度采集频率为每4小时1次。已对数据完成预处理：剔除记录仪未埋置于土壤中时的无效采集值，并针对土壤温度进行校准均衡。数据存储为逗号分隔的纯文本.csv文件，数据列依次为：样地编号、年份、年积日（Day of Year，DOY）、当日小时数、当日分钟数、年中日分数、年分数、摄氏温度。温度分辨率为0.5℃。
