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. Data has been deleted.

SoilEmp是科伯峡湾（Kobbefjord）三台自动土壤观测站之一。该站于2008年建成，设于河岸东侧的岩高兰（crowberry）植被带，海拔33米（m.a.s.l.）。观测站搭载CR1000型数据采集器（CR1000 logger），运行时区为西格陵兰冬季时间（WGWT）。土壤温度监测采用热电偶（thermocouple）105T型传感器，土壤热通量监测采用Hukseflux品牌HFP01型传感器，两类数据均每30分钟记录一次，详见数据集"SoilEmp 30 min"；土壤湿度监测采用Delta-T品牌ML2x与SM300型传感器，观测数据每6小时记录一次。关于6小时频次的观测数据说明如下：2018年7月至8月，50厘米深度处的ML2x土壤湿度传感器发生故障，于同年8月更换为Delta-T SM300型传感器。该更换后的传感器因与土壤接触不良导致数据异常，故2018年8月起的相关数据已被剔除。此外，2018年8月站点运维作业后，30厘米与50厘米深度处的土壤湿度传感器亦受影响，相关观测数据已全部删除。
