TY - Data T1 - Data set of active layer thickness of frozen soil in Juhugeng No. 7 Well in Muli Kuangqu, Qinghai Province (2023-2025) A1 - li run jie A1 - zhu yuan tao A1 - huang wen de DO - 10.12072/ncdc.db7667.2026 PY - 2026 DA - 2026-07-06 PB - National Cryosphere Desert Data Center AB - The dynamic change of the thickness of the active layer of permafrost is an important parameter to reveal the response of permafrost to climate warming, assess ecosystem stability and water conservation. In this study, pulseEKKO geological radar was used to obtain the thickness data of permafrost active layer under different processing conditions. This data has the following advantages: fast collection speed, high accuracy, and the detection time covers the period from December 2023 to March 2025.
