NCAR CESM2 model output prepared for CMIP6 FAFMIP faf-passiveheat

Coupled Model Intercomparison Project Phase 6 (CMIP6) datasets: These data include all datasets published for 'CMIP6.FAFMIP.NCAR.CESM2.faf-passiveheat' 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 CESM2 climate model, released in 2018, includes the following components:
aerosol: MAM4 (same grid as atmos), atmos: CAM6 (0.9x1.25 finite volume grid; 288 x 192 longitude/latitude; 32 levels; top level 2.25 mb), atmosChem: MAM4 (same grid as atmos), land: CLM5 (same grid as atmos), landIce: CISM2.1, ocean: POP2 (320x384 longitude/latitude; 60 levels; top grid cell 0-10 m), ocnBgchem: MARBL (same grid as ocean), seaIce: CICE5.1 (same grid as ocean).
The model was run by the National Center for Atmospheric Research, Climate and Global Dynamics Laboratory, 1850 Table Mesa Drive, Boulder, CO 80305, USA (NCAR) in native nominal resolutions: aerosol: 100 km, atmos: 100 km, atmosChem: 100 km, land: 100 km, landIce: 5 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.FAFMIP.NCAR.CESM2.faf-passiveheat`为标识发布的数据集，其完整数据引用语法遵循`mip_era.activity_id.institution_id.source_id.experiment_id.member_id.table_id.variable_id.grid_label.version`模板。

于2018年发布的CESM2气候模式包含以下组成模块：
气溶胶模块：MAM4（与大气模块网格一致）；大气模块：CAM6（采用0.9°×1.25°有限体积网格；经度/纬度格点数为288×192；共32层，顶层气压为2.25毫巴）；大气化学模块：MAM4（与大气模块网格一致）；陆面模块：CLM5（与大气模块网格一致）；陆冰模块：CISM2.1；海洋模块：POP2（经度/纬度格点数为320×384；共60层，顶层网格单元水深为0~10米）；海洋生物地球化学模块：MARBL（与海洋模块网格一致）；海冰模块：CICE5.1（与海洋模块网格一致）。

该模式由美国国家大气研究中心（National Center for Atmospheric Research，NCAR）气候与全球动力学实验室运行，机构地址为美国科罗拉多州博尔德市Table Mesa大道1850号，邮编80305，其采用的原生标称分辨率如下：气溶胶模块：100千米，大气模块：100千米，大气化学模块：100千米，陆面模块：100千米，陆冰模块：5千米，海洋模块：100千米，海洋生物地球化学模块：100千米，海冰模块：100千米。

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》（Geoscientific Model Development，GMD）特刊：http://www.geosci-model-dev.net/special_issue590.html）的一部分生成。该模拟数据为解答核心科学问题的气候研究提供了基础支撑，同时亦可作为政府间气候变化专门委员会（Intergovernmental Panel on Climate Change，IPCC）第六次评估报告（IPCC-AR6）撰稿人的参考资源。

耦合模式比较计划第六阶段由耦合模式工作组（Working Group on Coupled Modelling，WGCM）作为世界气候研究计划（World Climate Research Programme，WCRP）的组成部分进行协调管理。第六阶段依托此前在气候模式诊断与比对计划（Program for Climate Model Diagnosis and Intercomparison，PCMDI）主导下完成的多阶段项目建设，并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。原始数据存储于分布式数据节点集群中并进行部分副本备份，IPCC所依赖的绝大多数数据已交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个全球气候模式的模拟成果，以及来自全球约45家机构与组织的参与贡献。——项目官网：https://pcmdi.llnl.gov/CMIP6。
