IPCC DDC: MIROC MIROC-ES2L model output prepared for CMIP6 CMIP esm-hist

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.CMIP.MIROC.MIROC-ES2L.esm-hist' 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.

项目名称：耦合模型比对计划第六阶段（Coupled Model Intercomparison Project Phase 6，CMIP6）数据集——本数据集作为国际协调的耦合模型比对计划第六阶段（CMIP6）的产出成果，详见《地球科学模型开发》（GMD）特刊：http://www.geosci-model-dev.net/special_issue590.html。该模拟数据为解答核心科学问题的气候研究提供了支撑基础，同时亦是政府间气候变化专门委员会第六次评估报告（IPCC-AR6）作者团队的核心数据源。CMIP6由耦合模型工作组（Working Group on Coupled Modelling，WGCM）协调开展，隶属于世界气候研究计划（World Climate Research Programme，WCRP）。第六阶段承袭此前在气候模型诊断与比对计划（Program for Climate Model Diagnosis and Intercomparison，PCMDI）主导下开展的多轮次比对工作，依托地球系统网格联合会（Earth System Grid Federation，ESGF）、环境数据分析中心（Centre for Environmental Data Analysis，CEDA）及诸多相关配套活动完成项目落地。原始数据存储于分布式数据节点集群并实现部分副本共享；IPCC所依赖的绝大多数数据，目前正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。本项目涵盖全球约120个全球气候模型及45家科研机构与组织的模拟试验数据。
