IPCC DDC: MRI MRI-ESM2.0 model output prepared for CMIP6 DAMIP hist-GHG

Project: Coupled Model Intercomparison Project Phase 6 (CMIP6) datasets - These data have been generated as part of the internationally-coordinated Coupled Model Intercomparison Project Phase 6 (CMIP6; see also GMD Special Issue: http://www.geosci-model-dev.net/special_issue590.html). The simulation data provides a basis for climate research designed to answer fundamental science questions and serves as resource for authors of the Sixth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC-AR6). CMIP6 is a project coordinated by the Working Group on Coupled Modelling (WGCM) as part of the World Climate Research Programme (WCRP). Phase 6 builds on previous phases executed under the leadership of the Program for Climate Model Diagnosis and Intercomparison (PCMDI) and relies on the Earth System Grid Federation (ESGF) and the Centre for Environmental Data Analysis (CEDA) along with numerous related activities for implementation. The original data is hosted and partially replicated on a federated collection of data nodes, and most of the data relied on by the IPCC is being archived for long-term preservation at the IPCC Data Distribution Centre (IPCC DDC) hosted by the German Climate Computing Center (DKRZ). The project includes simulations from about 120 global climate models and around 45 institutions and organizations worldwide. Summary: These data include the subset used by IPCC AR6 WGI authors of the datasets originally published in ESGF for 'CMIP6.DAMIP.MRI.MRI-ESM2-0.hist-GHG' with the full Data Reference Syntax following the template 'mip_era.activity_id.institution_id.source_id.experiment_id.member_id.table_id.variable_id.grid_label.version'. The MRI-ESM2.0 climate model, released in 2017, includes the following components: aerosol: MASINGAR mk2r4 (TL95; 192 x 96 longitude/latitude; 80 levels; top level 0.01 hPa), atmos: MRI-AGCM3.5 (TL159; 320 x 160 longitude/latitude; 80 levels; top level 0.01 hPa), atmosChem: MRI-CCM2.1 (T42; 128 x 64 longitude/latitude; 80 levels; top level 0.01 hPa), land: HAL 1.0, ocean: MRI.COM4.4 (tripolar primarily 0.5 deg latitude/1 deg longitude with meridional refinement down to 0.3 deg within 10 degrees north and south of the equator; 360 x 364 longitude/latitude; 61 levels; top grid cell 0-2 m), ocnBgchem: MRI.COM4.4, seaIce: MRI.COM4.4. The model was run by the Meteorological Research Institute, Tsukuba, Ibaraki 305-0052, Japan (MRI) in native nominal resolutions: aerosol: 250 km, atmos: 100 km, atmosChem: 250 km, land: 100 km, ocean: 100 km, ocnBgchem: 100 km, seaIce: 100 km.

Project: 耦合模型比对项目第六阶段（Coupled Model Intercomparison Project Phase 6，CMIP6）数据集——本数据集作为国际协同统筹的耦合模型比对项目第六阶段（CMIP6；详见《地球科学模型开发》特刊：http://www.geosci-model-dev.net/special_issue590.html）的产出成果生成。该模拟数据可为解答核心科学问题的气候研究提供支撑，同时为政府间气候变化专门委员会第六次评估报告（Intergovernmental Panel on Climate Change Sixth Assessment Report，IPCC-AR6）的撰稿人员提供数据资源。CMIP6由耦合模拟工作组（Working Group on Coupled Modelling，WGCM）作为世界气候研究计划（World Climate Research Programme，WCRP）的组成部分统筹协调。第六阶段项目继承了此前由气候模型诊断与比对计划（Program for Climate Model Diagnosis and Intercomparison，PCMDI）主导开展的多阶段项目成果，依托地球系统网格联盟（Earth System Grid Federation，ESGF）、环境数据分析中心（Centre for Environmental Data Analysis，CEDA）及众多相关配套活动完成项目实施。原始数据托管于分布式数据节点联盟并实现部分镜像复制，IPCC所依赖的绝大多数数据将长期归档保存于由德国气候计算中心（German Climate Computing Center，DKRZ）运维的IPCC数据分发中心（IPCC Data Distribution Centre，IPCC DDC）。本项目汇聚了全球约120个全球气候模型与45家左右的科研机构及组织的模拟成果。
