%X This data set is aimed at the tuomu'er peak area of Tianshan Mountains, mainly including the keqikar glacier in the tuomu'er mountain area. The subglacial terrain data set includes the serial number, longitude, latitude and thickness of control points. The data set contains 258 records. The GPR ground penetrating radar (GPR) is mainly used to select the appropriate cross-section on the glacier surface, and the glacier thickness data at the cross-section position is obtained by actual measurement. The data set is only for the glacier thickness in 2008, 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 2008. 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.
