ZEROCALM-2_Soil_moisture

Soil moisture is measured every week, during the snow free season, along row 1 and 6 in the ZEROCALM-2 grid (row numbers and grid nodes can be found in the GeoBasis Zackenberg manual). Soil moisture is measured every 10th meter in each row. Measurements were initiated in 1997 (where only one measurement was made at each grid node), however measurements were paused until 2004, whereafter three replicates were made by each grid stone, if possible. Soil moisture is measured manually using a ThetaProbe which measures the soil moisture within the first 6 cm from the soil surface (indicated with 0-6_cm in the columnname).在无雪季期间，每周对ZEROCALM-2网格的第1行与第6行开展土壤湿度监测，行号及网格节点信息可查阅《GeoBasis Zackenberg手册》。每一行内每间隔10米进行一次测量。该监测工作于1997年启动，初始阶段每个网格节点仅开展一次测量；此后监测工作暂停，直至2004年恢复，后续若条件允许，每个网格节点将进行三次重复测量。土壤湿度采用ThetaProbe土壤水分传感器（ThetaProbe）手动测定，该传感器可测量土壤表层0至6厘米范围内的土壤湿度，该参数在列名中以0-6_cm标注。
