This data set is aimed at Gangri Gabu area, mainly including the Yalong glacier in Gangri Gabu area. The subglacial terrain data set includes the serial number, longitude, latitude and thickness of control points. The data set contains 46 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).
This data set is mainly measured data, and the main data source is GPR ground penetrating radar.
In the data measurement, GPR ground penetrating radar is used to select the appropriate cross-section on the glacier surface, and then the glacier thickness is calculated in the software.
Before using ground penetrating radar (GPR), the propagation velocity of radar wave velocity in glacier ice is measured, and the parameters of GPR are modified to ensure the most accurate thickness data of corresponding glacier.
