%X This data set is the artificial observation data set of frozen soil depth in Qilian station from January 1, 2011 to December 31, 2011, which is observed at 08:00 every day. The data content is frozen depth data set of permafrost. Frozen soil observation is based on the freezing depth (length) of water poured into the rubber inner pipe as a record, and the frozen layer and its upper and lower limit depth are determined according to the position and length of water freezing in the frozen soil. The unit of centimeter (CM) shall be rounded to the whole number. It was observed once every day at 08:00. Geographical coordinates: longitude: 99 ° 53 ′ E; latitude: 38 ° 16 ′ n; altitude: 2981.0m
