Comprehensive dataset of permafrost temperature along the Nenlin Railway (6 boreholes), covering the period from August 1, 2023 to March 25, 2024. The data was automatically collected through the thermistor temperature chain (developed by the State Key Laboratory of Cryosphere Science and Frozen Soil Engineering, with a measurement accuracy of ± 0.05 ℃) deployed on the site, and recorded by the CR3000 data acquisition instrument and the TRM128 deep hole temperature measurement expansion board, with a collection frequency of 2h/time. The raw observation data is calculated on a daily basis to generate daily scale data, forming a dataset. This dataset can be used for thermal characteristics analysis of frozen soil along pipelines, monitoring of frozen soil environments, research on engineering thermal disturbances, and related research on frozen soil disasters and environmental science.
The spatial location information of the table data is as follows:
Longitude (Tuqiang Water Plant North: 122.7209; Amur: 123.212653; Changying: 123.304782; Xiufeng: 124.587094; Taiyanggou: 124.281266; 94 kilometers: 124.184812)
Latitude (Tuqiang Water Plant North: 52.94937; Amur: 52.838268; Changying: 52.875296 Xiufeng: 52.498947; Taiyanggou: 51.310306; 94 kilometers: 51.149723)
The original observation data was automatically collected through the thermistor temperature chain (developed by the State Key Laboratory of Cryosphere Science and Frozen Soil Engineering, with a measurement accuracy of ± 0.05 ℃) deployed on the site, and recorded by the CR3000 data acquisition instrument and the TRM128 deep hole temperature measurement expansion board, with a collection frequency of 2h/time.
Set up 5 boreholes on site and use thermistor temperature chains for automatic observation, with a measurement accuracy of ± 0.05 ℃; The acquisition unit includes the CR3000 data acquisition instrument from Campbell Scientific in the United States and the TRM128 deep hole temperature measurement expansion board. The temperature probe is installed at a depth covering 0 to 25 meters, with a collection frequency of once every 2 hours.
Following standard specifications: The observation method complies with field monitoring standards and relevant technical requirements to ensure the accuracy and representativeness of monitoring data.
Processing method: The raw observation data is calculated on a daily basis to generate a daily average ground temperature dataset; The data has not been interpolated, simulated, or subjected to any other secondary calculation processing.
The collection equipment is regularly calibrated to ensure the continuity, accuracy, and scientific applicability of the data.
