Soil temperatures and moisture for Arctic Long Term Experimental Research (ARC LTER) heath experimental plots,Toolik Field Station, North Slope Alaska for 2001-2023.

**Note:** In version 1 the moisture columns were mixed up. The fractional volumetric water columns were actually the period frequency of the wave of the sensor (Campbell Scientific CS616). Soil temperatures at 2 depths, 5 and 10 cm, canopy temperatures and soil moisture at 10 cm were measured in an Arctic Long Term Experimental Research (ARC-LTER) heath tundra site (DHT89) at Toolik Lake Field Station, North slope, Alaska. Air temperature and relative humidity and global radiation were also measured but are presented in another dataset. Only control and nutrient addition (nitrogen plus phosphorus ) treatments plots were measured .

注意：在版本1中，水分列存在混淆问题。原标注为体积含水量的列，实际对应的是Campbell Scientific CS616型传感器的波周期频率。本次测量的样地位于阿拉斯加北坡图利克湖野外站的北极长期试验研究（ARC-LTER）冻原灌丛样地（DHT89），测量指标包括5cm、10cm两个深度的土壤温度、冠层温度以及10cm深度的土壤含水量。气温、相对湿度与总辐射虽同步开展观测，但相关数据已收录于另一数据集。本数据集仅覆盖对照组与养分添加（氮+磷）处理的样地。
