T1-Temperature_125m

T1 is a basic mast where ground surface temperature and air temperature (2 meter above ground) are measured. The mast was installed in August 2014. It is located on the top of Pjeturssons moraine ridge (125 meter above sea level) on a surface covered by low dwarf shrub vegetation. The time stamp refer to West Greenland Standard Time (UTC-3). Similar masts are found at other altitudes covering a gradient from 0 to 830 m above sea level (T2-temperature_830m, T3-temperature_400m, T4-Temperature_1m).T1为基础型气象观测塔，用于测量地表温度与距地面2米高度处的气温。该观测塔于2014年8月完成架设，选址于佩图尔松冰碛脊（Pjeturssons moraine ridge）顶部，海拔125米，地表覆盖低矮灌丛植被。本数据集的时间戳采用西格陵兰标准时间（UTC-3）。其余不同海拔高度处均设有同类型观测塔，覆盖海拔梯度范围为0至830米，对应观测站点分别为T2-temperature_830m、T3-temperature_400m及T4-Temperature_1m。
