北半球冻土顶板温度与活动层厚度0.625°x0.4712°栅格数据集（2015-2100）

作者运用广泛验证的半经验模型Kudryavtsev方法，综合温度、积雪、植被、土壤等对冻土的影响因素，以国际耦合模式比较计划第六阶段（CMIP6）模式模拟结果和SoilGrids 2.0数据集等作为模型输入，计算了2015-2100年北半球冻土顶板温度与活动层厚度在SSP126、SSP245、SSP370和SSP585四种情景下的逐年时间序列，并根据顶板温度计算了北半球未来四种情境下冻土分布面积。数据集包括2015-2100年逐年以下实验数据：（1）冻土顶板温度数据；（2）活动层厚度数据；（3）冻土面积数据。数据集存储为.tif和.xls格式，空间分辨率为0.625°x0.4712°，由690个数据文件组成，数据量为35.6 MB（压缩为1个文件，27.9 MB）。

The authors utilized the widely validated semi-empirical Kudryavtsev method, incorporating the impacts of multiple factors including temperature, snow cover, vegetation and soil on permafrost. Using the simulation outputs of Coupled Model Intercomparison Project Phase 6 (CMIP6) models and the SoilGrids 2.0 dataset as well as other relevant datasets as model inputs, they calculated the annual time series of permafrost table temperature and active layer thickness in the Northern Hemisphere under four SSP scenarios (SSP126, SSP245, SSP370 and SSP585) from 2015 to 2100, and estimated the permafrost distribution area in the Northern Hemisphere under the four future scenarios based on the permafrost table temperature. The dataset includes the following annual data from 2015 to 2100: (1) permafrost table temperature data; (2) active layer thickness data; (3) permafrost area data. The dataset is stored in .tif and .xls formats, with a spatial resolution of 0.625°×0.4712°, consisting of 690 individual data files, with a total uncompressed size of 35.6 MB, which is compressed into a single file of 27.9 MB.
