%X This dataset is a manually observed frozen soil depth dataset from Qilian Station from January 1, 2014 to December 31, 2014, with daily observations at 08:00. The data content is a frozen depth dataset of permafrost. Frozen soil observation uses the freezing depth (length) of water poured into a rubber tube as a record to determine the freezing level and its upper and lower limit depths based on the location and length of water freezing in the frozen soil container buried in the soil. Round whole numbers to the nearest integer in centimeters (cm). Observe once a day at 08:00. Geographic coordinates: longitude: 99 ° 53'E; latitude: 38 ° 16'N; altitude: 2981.0m
