可可西里典型冻融滑坡（热融滑塌）监测数据（2020-2022）

该数据集为位于可可西里地区红梁河附近（92.975°E, 34.996°N）典型热融滑塌地温监测数据，数据包括未滑塌区和已滑塌区两个监测点连续监测数据。测温探头采用冻土工程国家重点实验自主研制的高精度热敏电阻探头，测温精度0.05℃，数据采集和存储采用CR3000型数采仪。观测时间在2020年1月1日-2022年3月1日之间。地温观测时间间隔1日，地温的观测深度为15m，其中0-10m为每0.5m一个测温探头，10-15m为每1m一个测温探头。质量控制包括剔除传感器未完全适应土壤环境时的数据和传感器出现故障造成的系统误差。经过矫正的最终数据以excel文件存储。获取的现场数据经多人复查审核，数据完整性和准确度达到95%以上。监测数据可为后期开展青藏高原多年冻土区热融滑塌相关研究工作提供必要的数据支撑。

This dataset contains typical ground temperature monitoring data of thermokarst slumps near Hongliang River in the Hoh Xil region (92.975°E, 34.996°N). The data comes from two continuous monitoring sites: an unslumped area and a slumped area. High-precision thermistor probes independently developed by the State Key Laboratory of Frozen Soil Engineering were used for temperature measurement, with an accuracy of 0.05℃. Data collection and storage were carried out using a CR3000 data logger. The observation period was from January 1, 2020 to March 1, 2022. The ground temperature was monitored at a 1-day interval, with a monitoring depth of 15 m. Temperature probes were installed every 0.5 m from 0 to 10 m, and every 1 m from 10 to 15 m. Quality control included removing data collected when the sensors had not fully adapted to the soil environment and systematic errors caused by sensor malfunctions. The finalized corrected data is stored in Excel files. The collected field data was reviewed and verified by multiple personnel, with data integrity and accuracy exceeding 95%. This monitoring dataset can provide essential data support for subsequent research on thermokarst slumps in the permafrost regions of the Qinghai-Tibet Plateau.
