thule_tram_soil_temp_winter_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 2012 DOY228 and left in place to measure winter temperature during 2012 and 2013, removed DOY165 in 2013. 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, fractional day of year, temperature in C, fractional year. Temperature resolution is 0.5 C.

本数据集包含格陵兰图勒空军基地附近一条长度逾55米的样带沿线约10厘米深度处的土壤温度数据，该样带覆盖了从湿苔原到极地半荒漠的环境梯度。本次监测采用温度记录微器（iButton），该设备于2012年第228个年中日（DOY228）布设至样带中，原位持续采集2012至2013年冬季的土壤温度，并于2013年第165个年中日（DOY165）被移除。温度采集频率为每4小时一次。已对原始数据进行预处理：剔除温度记录微器未埋入土壤时段的无效数据，并针对土壤温度条件完成均衡校正。数据格式为逗号分隔符文本（CSV），各数据列依次为：样地编号、年份、年中日、当日时刻、年中日小数位、温度（单位：摄氏度）、年度小数位。本数据集的温度分辨率为0.5摄氏度。
