%K GPR;ice thickness;Eastern Grantham peak
%X This data set is aimed at the eastern peak of gradan. The data set includes the serial number, longitude, latitude and thickness of control points. The data set contains 43 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.
