本数据集针对念青唐古拉山主峰地区，主要包括念青唐古拉山主峰卡里干冰川，冰下地形数据集包括控制点的序号、经度、纬度、厚度。数据集包含19条记录，主要利用GPR探地雷达，在冰川表面选取适当位置的横截面，通过实测获取的该横截面位置冰川厚度数据。数据集只针对2015年当年冰川厚度，故不进行补充和完善，采用协议共享。数据集包含控制点的序号、经度（单位：度(°)）、纬度（单位：度(°)）、高程（单位：米(m)，即当年冰川厚度）4个字段。数据集主要为当年实测资料，时间为2015年8月。空间基准为WGS84/EGM96，用探地雷达测量前，先进行雷达波速在冰川冰内传播速度的测量，并对探地雷达相关参数进行修改，确保获取对应冰川最精确的厚度数据。

The data set contains 19 records, mainly using GPR ground penetrating radar to select the appropriate cross-section on the glacier surface, and obtain the glacier thickness data of the cross-section position through the actual measurement. The data set is only for the glacier thickness in 2015, so it is not supplemented and improved, and the protocol is used for sharing. The data set contains four fields: serial number, longitude (unit: Degree (°)), latitude (unit: Degree (°)) and elevation (unit: meter (m), that is, glacier thickness of the current year). The data set is mainly the measured data in August 2015. The spatial datum is WGS84 / EGM96. Before using GPR, the propagation velocity of radar wave velocity in glacier ice is measured, and the relevant parameters of GPR are modified to ensure the most accurate thickness data of corresponding glacier.
