Secondary ISIMIP3b bias-adjusted atmospheric climate input data

The Inter-Sectoral Impact Model Intercomparison Project (ISIMIP) provides a framework for the collation of a consistent set of climate impact data across sectors and scales. It also provides a unique opportunity for considering interactions between climate change impacts across sectors through consistent scenarios.<br>The ISIMIP3b part of the third simulation round is dedicated to a quantification of climate-related risks at different levels of global warming and socio-economic change. ISIMIP3b group I simulations are based on historical climate change as simulated in CMIP6 combined with observed historical socio-economic forcing. ISIMIP3b group II simulations are based on climate change according to the CMIP6 future projections combined with socio-economic forcings fixed at 2015 levels. ISIMIP3b group III simulations additionally account for future changes in socio-economic forcing.<br>This dataset covers additional CMIP6-based and bias-adjusted atmospheric climate input data published as secondary input data for ISIMIP3b. Included are datasets from the 5 CMIP6 global climate models that are included in the ISIMIP3b protocol (GFDL-ESM4, IPSL-CM6A-LR, MPI-ESM1-2-HR, MRI-ESM2-0, UKESM1-0-LL) for experiments which are not part of the ISIMIP3b protocol (hist-nat, ssp119, ssp245, ssp460, ssp534-over). Also included are datasets from 5 additional CMIP6 global climate models (CNRM-CM6-1, CNRM-ESM2-1, CanESM5, EC-Earth3, MIROC6) for the experiments of the ISIMIP3b protocol (piControl, historical, SSP126, SSP370, SSP585) and hist-nat in some cases.<br>Version 1.1 of this dataset adds files for the ssp534-over scenario.

跨部门影响模型比对项目（Inter-Sectoral Impact Model Intercomparison Project, ISIMIP）搭建了一套可跨部门、跨尺度整合一致气候影响数据的研究框架，同时为通过统一情景探究部门间气候变化影响的交互机制提供了独特契机。
第三轮模拟周期中的ISIMIP3b部分，旨在量化不同全球增温水平与社会经济变化情境下的气候相关风险。其中ISIMIP3b第一组模拟以耦合模式比较计划第六阶段（Coupled Model Intercomparison Project Phase 6, CMIP6）模拟得到的历史气候变化结果，结合观测得到的历史社会经济强迫作为驱动；第二组模拟采用CMIP6未来情景的气候变化预估结果，并将社会经济强迫固定于2015年水平；第三组模拟则额外纳入了社会经济强迫的未来变化。
本数据集涵盖了作为ISIMIP3b二级输入数据发布的、基于CMIP6且经偏差校正的大气气候输入数据。具体包含两类数据集：一是符合ISIMIP3b方案的5个CMIP6全球气候模型（GFDL-ESM4、IPSL-CM6A-LR、MPI-ESM1-2-HR、MRI-ESM2-0、UKESM1-0-LL）在非ISIMIP3b方案实验（hist-nat、共享社会经济路径119（ssp119）、共享社会经济路径245（ssp245）、共享社会经济路径460（ssp460）、共享社会经济路径534-over（ssp534-over））下的数据集；二是额外5个CMIP6全球气候模型（CNRM-CM6-1、CNRM-ESM2-1、CanESM5、EC-Earth3、MIROC6）在ISIMIP3b方案实验（piControl、historical、共享社会经济路径126（SSP126）、共享社会经济路径370（SSP370）、共享社会经济路径585（SSP585））及部分hist-nat实验下的数据集。
本数据集V1.1版本新增了共享社会经济路径534-over（ssp534-over）情景对应的相关数据文件。
