NOAA-GFDL GFDL-ESM4 model output prepared for CMIP6 CMIP

Coupled Model Intercomparison Project Phase 6 (CMIP6) datasets: These data include all datasets published for 'CMIP6.CMIP.NOAA-GFDL.GFDL-ESM4' 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 GFDL-ESM4 climate model, released in 2018, includes the following components:
aerosol: interactive, atmos: GFDL-AM4.1 (Cubed-sphere (c96) - 1 degree nominal horizontal resolution; 360 x 180 longitude/latitude; 49 levels; top level 1 Pa), atmosChem: GFDL-ATMCHEM4.1 (full atmospheric chemistry), land: GFDL-LM4.1, landIce: GFDL-LM4.1, ocean: GFDL-OM4p5 (GFDL-MOM6, tripolar - nominal 0.5 deg; 720 x 576 longitude/latitude; 75 levels; top grid cell 0-2 m), ocnBgchem: GFDL-COBALTv2, seaIce: GFDL-SIM4p5 (GFDL-SIS2.0, tripolar - nominal 0.5 deg; 720 x 576 longitude/latitude; 5 layers; 5 thickness categories).
The model was run by the National Oceanic and Atmospheric Administration, Geophysical Fluid Dynamics Laboratory, Princeton, NJ 08540, USA (NOAA-GFDL) in native nominal resolutions: aerosol: 100 km, atmos: 100 km, atmosChem: 100 km, land: 100 km, landIce: 100 km, ocean: 50 km, ocnBgchem: 50 km, seaIce: 50 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：本数据集包含所有针对「CMIP6.CMIP.NOAA-GFDL.GFDL-ESM4」发布的数据集，其完整数据引用语法（Data Reference Syntax）遵循模板：`mip_era.activity_id.institution_id.source_id.experiment_id.member_id.table_id.variable_id.grid_label.version`。

于2018年发布的GFDL-ESM4气候模式包含以下组成部分：气溶胶模块：交互式运行；大气模块：GFDL-AM4.1（采用立方球网格（Cubed-sphere, c96），名义水平分辨率为1°，经纬度网格尺寸为360×180，垂直分层49层，顶层气压为1 Pa）；大气化学模块：GFDL-ATMCHEM4.1（完整大气化学模块）；陆面模块：GFDL-LM4.1；陆冰模块：GFDL-LM4.1；海洋模块：GFDL-OM4p5（基于GFDL-MOM6，采用三极网格，名义分辨率0.5°，经纬度网格尺寸为720×576，垂直分层75层，表层网格水深范围为0~2 m）；海洋生物地球化学模块：GFDL-COBALTv2；海冰模块：GFDL-SIM4p5（基于GFDL-SIS2.0，采用三极网格，名义分辨率0.5°，经纬度网格尺寸为720×576，垂直分为5层，包含5个厚度分类）。

本模式由美国新泽西州普林斯顿市美国国家海洋和大气管理局地球物理流体动力学实验室（National Oceanic and Atmospheric Administration, Geophysical Fluid Dynamics Laboratory, Princeton, NJ 08540, USA，简称NOAA-GFDL）以原生名义分辨率运行，各模块分辨率分别为：气溶胶模块100 km、大气模块100 km、大气化学模块100 km、陆面模块100 km、陆冰模块100 km、海洋模块50 km、海洋生物地球化学模块50 km、海冰模块50 km。

项目背景：本数据集作为国际协调的耦合模式比较计划第六阶段（CMIP6；详见《地球科学模式发展》特刊：http://www.geosci-model-dev.net/special_issue590.html）的产出成果之一，其模拟数据可为解答基础科学问题的气候研究提供支撑，同时也是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）作者群体的核心参考资源。

CMIP6由耦合模式工作组（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）。第六阶段依托此前在气候模式诊断与比较计划（Program for Climate Model Diagnosis and Intercomparison, PCMDI）主导下完成的多轮前期计划，同时借助地球系统网格联盟（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实施。

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 Data Distribution Centre, IPCC DDC）进行长期归档保存。

本项目涵盖全球约120个全球气候模式的模拟试验，参与单位达45家左右。——项目官网：https://pcmdi.llnl.gov/CMIP6。
