CMIP6 Global and pan-Arctic Temperature

Annually averaged surface-air temperature from CMIP6 models for the following experiments: historical, ssp126, ssp245, and ssp585. Also included is the average of four observational records: Berkeley Earth (1850-2014), GISTemp v4 (1880-2014), HadCRUT4.6.0.0 (1850-2014) and NOAAGlobalTemp v5 (1880-2014). Before an overall average is calculated, the Berkeley Earth and HadCRUT datasets are extrapolated for the 1850-1879 period based on their linear relationship with the average of the GISTemp and NOAAGlobalTemp records. The column "tglobal" includes the globally averaged temperature (K), and "tregion" includes the average temperature for the region north of 60°N.

本数据集包含耦合模式比较计划第六阶段（CMIP6，Coupled Model Intercomparison Project Phase 6）模式的逐年地表气温数据，涵盖以下试验场景：historical（历史模拟试验）、ssp126、ssp245及ssp585。此外还收录了四份观测记录的平均结果：伯克利地球（Berkeley Earth，1850-2014）、GISTemp v4（1880-2014）、HadCRUT4.6.0.0（1850-2014）以及NOAAGlobalTemp v5（1880-2014）。在计算整体平均气温前，本数据集基于伯克利地球、HadCRUT数据集与GISTemp、NOAAGlobalTemp记录平均值的线性相关关系，对二者1850-1879年时段的数据进行了外推补全。数据列"tglobal"代表全球平均气温（单位：开尔文，K），"tregion"代表北纬60°以北区域的平均气温。
