Daily soil temperature and moisture records (2018-2019) from observation site GEC-1801 in the Argentinian Andes

Soil temperature (°C) and water saturation (%) were collected in the uppermost levels of the active layer from “El Candidato” rock glacier, from 2018 to 2019. “El Candidato” is an active rock glacier placed in the Argentinian Central Andes at 4012 m.a.s.l. (31.898672°S; 70.178486°W). The purpose of the data set was to analyze the volumetric water content and ground temperature variation in the landform frontal talus, in terms of active layer depth estimation. Four investigation depths were selected: 5 cm, 25 cm, 50 cm and 70 cm. Lectures were made 6 times a day, at 02:00, 06:00, 10:00, 14:00, 18:00 and 22:00 hours (GMT-3), from 17/04/2018 to 26/03/2019 with 4 SMT-100 data loggers (TRUEBNER GmbH, Germany). Soil temperature and water saturation were calculated as the average of the six daily data, considering for the last one site-specific porosity estimations.

2018年至2019年间，科研团队于“埃尔坎迪达托（El Candidato）”活动岩冰川的多年冻土活动层最上层采集了土壤温度（单位：摄氏度）与水分饱和度（单位：百分比）数据。“埃尔坎迪达托”是一处坐落于阿根廷中部安第斯山脉、海拔4012米（南纬31.898672°，西经70.178486°）的活动岩冰川。本数据集旨在分析该地貌前缘倒石堆的体积含水量与地温变化，用于开展活动层厚度估算研究。研究选取了4个探测深度：5 cm、25 cm、50 cm与70 cm。实验采用4台SMT-100型数据记录仪（德国TRUEBNER GmbH公司），于2018年4月17日至2019年3月26日期间，以格林尼治标准时间减3小时（GMT-3）的02:00、06:00、10:00、14:00、18:00及22:00为采样时刻，每日开展6次数据采集。最终土壤温度与水分饱和度以每日6次采集数据的平均值计算，其中水分饱和度的计算需结合对应测点的孔隙度估算值。
