"Circum-Arctic active layer thickness rasters"
These data represent the active layer thickness (ALT, in cm) forecasts over northern hemisphere land areas (>30°N) presented in the manuscript by Aalto et al., (2018) "Statistical forecasting of current and future circum-Arctic ground temperatures and active layer thickness" published in Geophysical Research Letters. The data has been produced for several time periods and representative concentration pathways (RCP), and they represent the ensemble median of four statistical modelling techniques:
ALT_Baseline.tif # Forecasted ALT 2000-2014
ALT_2050RCP26.tif # 2041-2060 RCP 2.6
ALT_2050RCP45.tif # 2041-2060 RCP 4.5
ALT_2050RCP85.tif # 2041-2060 RCP 8.5
ALT_2070RCP26.tif # 2061-2080 RCP 2.6
ALT_2070RCP45.tif # 2061-2080 RCP 4.5
ALT_2070RCP85.tif # 2061-2080 RCP 8.5
Coordinate reference system = WGS84 (epsg:4326), spatial resolution = 30 arc seconds

环北极活动层厚度栅格数据集
本数据集包含Aalto等学者2018年发表于《地球物理研究快报》（Geophysical Research Letters）的论文《当前及未来环北极地温与活动层厚度统计预测》中提出的北半球陆地区域（纬度≥30°N）活动层厚度（Active Layer Thickness，缩写ALT，单位：厘米）预测结果。数据集针对多个时段与典型浓度路径（Representative Concentration Pathways，缩写RCP）情景生成，为四种统计建模方法的集合中位数结果：
ALT_Baseline.tif # 2000-2014年预测活动层厚度数据
ALT_2050RCP26.tif # 2041-2060时段、RCP 2.6情景下预测数据
ALT_2050RCP45.tif # 2041-2060时段、RCP 4.5情景下预测数据
ALT_2050RCP85.tif # 2041-2060时段、RCP 8.5情景下预测数据
ALT_2070RCP26.tif # 2061-2080时段、RCP 2.6情景下预测数据
ALT_2070RCP45.tif # 2061-2080时段、RCP 4.5情景下预测数据
ALT_2070RCP85.tif # 2061-2080时段、RCP 8.5情景下预测数据
坐标参考系统为WGS84（epsg:4326），空间分辨率为30角秒
