thule_tram_soil_temps_2013.csv

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本数据集为格陵兰图勒空军基地周边一条长度超55米的样带上，约10厘米深度处的土壤温度监测数据。该样带的生境梯度涵盖湿苔原至极地半荒漠的过渡区域。温度记录器（iButton）于2013年第166个年积日（DOY166）部署，于2012年第222个年积日（DOY222）回收。每4小时采集一次温度数据。数据已完成预处理：剔除温度记录器未埋入土壤时的无效采集值，并针对土壤温度进行均衡校准。数据格式为逗号分隔的CSV文本文件。数据列依次为：样地编号、年份、年积日、当日小时数、小时内分钟数、年积日小数形式、年份小数形式、摄氏温度。温度分辨率为0.5℃。
