Active layer thickness derived from ground-based soil temperature measurements in Lena River basin, 1957-2013

Time series of the departure of active layer thickness from its long-term mean across 25 stations in the Lena River basin from the mid-1950s through 2013. The maximum depth of the 0 ?C isotherm (i.e., active layer thickness) is determined by linear interpolation between two adjacent depths.Please cite: Wang, K.; Zhang, T.; Yang, D.

本数据集涵盖1950年代中期至2013年期间，勒拿河流域（Lena River basin）内25个观测站点的活动层厚度（active layer thickness）距其长期平均值的距平时间序列。0℃等温线的最大深度即为活动层厚度，该值通过相邻两个深度的线性插值法确定。请引用：Wang, K.; Zhang, T.; Yang, D. 俄罗斯北极流域多年冻土动态及其水文影响. *Adv. Clim. Chang. Res.*, 2021, 12: 482–498. https://doi.org/10.1016/j.accre.2021.03.014
