Temperature data recorded with Thermochron iButton data loggers in 2018 in Hengill, a sub-arctic geothermal area in SW-Iceland (64°03’N; 21°18’W, ~360 m.a.s.l.)

This data set includes temperature data recorded with Thermochron iButton data loggers in 2018. The data comprises 40 pairs of data loggers of which one was located belowground (buried at 10 cm depth) in order to measure soil temperature, and one was located aboveground (10 cm aboveground, on the top of white plastic tubes stuck in the ground, and covered with grey duct tape) in order to measure air temperature. The loggers recorded temperature every 3 hours from October 2017 until June 5th, 2018. The data also includes a measure of instant soil temperature measured in May at the same point where the pair of loggers was located.

本数据集包含2018年通过Thermochron iButton数据记录仪（Thermochron iButton data loggers）采集的温度数据。本次数据集共包含40组数据记录仪对：每组记录仪中一台埋设于地下10厘米处以采集土壤温度，另一台安装于地面以上10厘米处的白色塑料管顶端（塑料管插入土壤中，顶端覆有灰色布基胶带）以采集空气温度。该记录仪的采集频率为每3小时一次，采集时段为2017年10月至2018年6月5日。本数据集同时包含2017年5月在每组记录仪对应测点测得的瞬时土壤温度数据。
