SoilEmp 6h

SoilEmp is one of the three automatic soil stations in Kobbefjord. The station was established in 2008 and is placed on empetrum (crowberry) vegetation on the eastern side of the river 33 m.a.s.l. The station (CR1000 logger) is running West Greenlandic Winter time (WGWT). Soil temperatures (thermocouple, 105T) and soil heat flux (hukseflux, HFP01) are logged every 30 minutes (see SoilEmp 30 min), while the soil moisture (Delta-T, ML2x and SM300) is logged every six hours. Comments for six hour data: The ML2x soil moisture sensor in 50 cm depth was broken in July/August 2018 and was changed in August to a Delta-T, SM300 sensor. The new sensor showed bad data maybe due to bad contact to the soil and is deleted from August 2018. The soil moisture sensors in 30 cm and 50 cm depth also seem to be affected after the station work in August 2018. Therefore the time series of soil moisture data have been divided in a dataset before and after the station work in August 2018. Soil moisutre data from SoilEmp after August 2018 is located in the timeseries SoilEmp 6h_2020-.SoilEmp是科伯峡湾（Kobbefjord）地区三座自动土壤监测站之一。该监测站始建于2008年，设于河畔东侧的岩高兰（crowberry）植被带，海拔33米（m.a.s.l.）。监测站采用CR1000型数据记录仪（CR1000 logger），运行西格陵兰冬季时间（WGWT）。 土壤温度（热电偶式105T传感器）与土壤热通量（Hukseflux HFP01型传感器）的观测数据每30分钟记录一次（详见"SoilEmp 30 min"数据集）；土壤湿度（Delta-T品牌ML2x与SM300型传感器）则每6小时记录一次。 6小时频次观测数据说明如下：2018年7月至8月间，深度50厘米处的ML2x土壤湿度传感器发生故障，同年8月更换为Delta-T SM300型传感器。由于疑似与土壤接触不良，更换后的传感器产出异常数据，该批次数据自2018年8月起已被剔除。2018年8月站点维护作业后，深度30厘米与50厘米处的土壤湿度传感器亦受异常影响。据此，土壤湿度时间序列数据已以2018年8月站点维护为界，划分为前后两个独立数据集。2018年8月之后的SoilEmp土壤湿度数据，收录于"SoilEmp 6h_2020-"时间序列数据集。
