MRI MRI-ESM2.0 model output prepared for CMIP6 CMIP historical

Coupled Model Intercomparison Project Phase 6 (CMIP6) datasets: These data include all datasets published for 'CMIP6.CMIP.MRI.MRI-ESM2-0.historical' 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: 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. - Project website: https://pcmdi.llnl.gov/CMIP6.

耦合模式比较计划第六阶段（Coupled Model Intercomparison Project Phase 6，CMIP6）数据集：本数据集涵盖所有以'mip_era.activity_id.institution_id.source_id.experiment_id.member_id.table_id.variable_id.grid_label.version'为完整数据引用语法模板发布的'CMIP6.CMIP.MRI.MRI-ESM2-0.historical'相关数据集。

该MRI-ESM2.0气候模式于2017年发布，包含以下分量模块：气溶胶模块：MASINGAR mk2r4（TL95分辨率；经纬向网格为192×96；垂直分层80层；顶层气压为0.01 hPa）；大气模块：MRI-AGCM3.5（TL159分辨率；经纬向网格为320×160；垂直分层80层；顶层气压为0.01 hPa）；大气化学模块：MRI-CCM2.1（T42分辨率；经纬向网格为128×64；垂直分层80层；顶层气压为0.01 hPa）；陆面模块：HAL 1.0；海洋模块：MRI.COM4.4（采用主要为0.5°纬距/1°经距的三极网格，在赤道南北10°范围内经向分辨率加密至0.3°；经纬向网格为360×364；垂直分层61层；顶层网格深度范围为0~2 m）；海洋生物地球化学模块：MRI.COM4.4；海冰模块：MRI.COM4.4。

该模式由位于日本茨城县筑波市（邮编305-0052）的气象研究所（Meteorological Research Institute，MRI）以原始标称分辨率运行：气溶胶模块250 km，大气模块100 km，大气化学模块250 km，陆面模块100 km，海洋模块100 km，海洋生物地球化学模块100 km，海冰模块100 km。

本数据集作为国际协调开展的耦合模式比较计划第六阶段（CMIP6，详见《Geoscientific Model Development》特刊：http://www.geosci-model-dev.net/special_issue590.html）的产出成果生成。该模拟数据为旨在解答核心科学问题的气候研究提供支撑，同时可为政府间气候变化专门委员会第六次评估报告（IPCC-AR6）的撰稿人提供数据资源。

CMIP6由世界气候研究计划（World Climate Research Programme，WCRP）下属的耦合模式工作组（Working Group on Coupled Modelling，WGCM）协调推进。第六阶段延续了此前在气候模式诊断与比较计划（Program for Climate Model Diagnosis and Intercomparison，PCMDI）主导下开展的多轮耦合模式比较工作，依托地球系统网格联盟（Earth System Grid Federation，ESGF）与环境数据分析中心（Centre for Environmental Data Analysis，CEDA）及众多相关配套活动完成项目落地。原始数据托管于分布式数据节点联盟并实现部分副本存储，IPCC所依赖的绝大多数数据将由德国气候计算中心（German Climate Computing Center，DKRZ）托管的IPCC数据分发中心（IPCC DDC）进行长期归档保存。

该项目汇聚了全球约120个全球气候模式与近45家科研机构与组织的参与。——项目官网：https://pcmdi.llnl.gov/CMIP6。
