MIROC MIROC-ES2L model output prepared for CMIP6 PMIP midHolocene

Coupled Model Intercomparison Project Phase 6 (CMIP6) datasets: These data include all datasets published for 'CMIP6.PMIP.MIROC.MIROC-ES2L.midHolocene' 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 MIROC-ES2L climate model, released in 2018, includes the following components:
aerosol: SPRINTARS6.0, atmos: CCSR AGCM (T42; 128 x 64 longitude/latitude; 40 levels; top level 3 hPa), land: MATSIRO6.0+VISIT-e ver.1.0, ocean: COCO4.9 (tripolar primarily 1deg; 360 x 256 longitude/latitude; 63 levels; top grid cell 0-2 m), ocnBgchem: OECO ver.2.0; NPZD-type with C/N/P/Fe/O cycles, seaIce: COCO4.9.
The model was run by the JAMSTEC (Japan Agency for Marine-Earth Science and Technology, Kanagawa 236-0001, Japan), AORI (Atmosphere and Ocean Research Institute, The University of Tokyo, Chiba 277-8564, Japan), NIES (National Institute for Environmental Studies, Ibaraki 305-8506, Japan), and R-CCS (RIKEN Center for Computational Science, Hyogo 650-0047, Japan) (MIROC) in native nominal resolutions: aerosol: 500 km, atmos: 500 km, land: 500 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：本数据集包含所有以「CMIP6.PMIP.MIROC.MIROC-ES2L.midHolocene」为标识发布的数据集，其完整数据引用语法遵循模板「mip_era.activity_id.institution_id.source_id.experiment_id.member_id.table_id.variable_id.grid_label.version」。

发布于2018年的MIROC-ES2L气候模式包含以下组成模块：气溶胶模块为SPRINTARS6.0；大气模块为CCSR AGCM（分辨率为T42，即经纬度网格128×64，垂直层数40层，顶层气压3 hPa）；陆面模块为MATSIRO6.0+VISIT-e 1.0版本；海洋模块为COCO4.9（采用准极地方格网格，基础分辨率1°，经纬度网格360×256，垂直层数63层，顶层网格水深0~2 m）；海洋生物地球化学模块为OECO 2.0版本，属于包含碳（C）、氮（N）、磷（P）、铁（Fe）、氧（O）循环的NPZD型模块；海冰模块为COCO4.9。

该模式由以下机构联合运行：日本海洋·地球科学技术振兴机构（Japan Agency for Marine-Earth Science and Technology, JAMSTEC，神奈川县236-0001）、东京大学大气海洋研究所（Atmosphere and Ocean Research Institute, The University of Tokyo, AORI，千叶县277-8564）、日本国立环境研究所（National Institute for Environmental Studies, NIES，茨城县305-8506）以及理化学研究所计算科学研究中心（RIKEN Center for Computational Science, R-CCS，兵库县650-0047）（MIROC团队），其默认标称分辨率如下：气溶胶模块500 km，大气模块500 km，陆面模块500 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的耦合模式比较计划第六阶段（Coupled Model Intercomparison Project Phase 6，CMIP6；详见《地球模式发展》特刊：http://www.geosci-model-dev.net/special_issue590.html）的一部分生成。这套模拟数据可为解答核心科学问题的气候研究提供支撑，同时作为政府间气候变化专门委员会第六次评估报告（IPCC-AR6）作者的参考资料。

耦合模式比较计划第六阶段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）协调实施。第六阶段继承了此前由气候模式诊断与比较计划（Program for Climate Model Diagnosis and Intercomparison, PCMDI）主导开展的多阶段研究基础，其运行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），并配套多项相关活动。原始数据托管于联邦化的数据节点集群并实现部分镜像复制，IPCC依赖的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 Data Distribution Centre, IPCC DDC）进行长期归档保存。

该项目涵盖全球约120个全球气候模式与约45家科研机构及组织的模拟研究。——项目官网：https://pcmdi.llnl.gov/CMIP6。
