NCAR CESM1-CAM5-SE-HR model output prepared for CMIP6 HighResMIP control-1950

Coupled Model Intercomparison Project Phase 6 (CMIP6) datasets: These data include all datasets published for 'CMIP6.HighResMIP.NCAR.CESM1-CAM5-SE-HR.control-1950' 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 CESM 1.3 CAM5 spectral element configuration with CMIP5 forcings, hi res climate model, released in 2012, includes the following components:
aerosol: MAM3 (same grid as atmos), atmos: CAM5.2 (0.25 degree spectral element; 777602 cells; 30 levels; top level 2.25 mb), atmosChem: MAM3 (same grid as atmos), land: CLM4 (same grid as atmos), ocean: POP2 (3600x2400 longitude/latitude; 62 levels; top grid cell 0-10 m), ocnBgchem: "BEC (same grid as ocean), seaIce: CICE4 (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: 25 km, atmos: 25 km, atmosChem: 25 km, land: 25 km, ocean: 10 km, ocnBgchem: 10 km, seaIce: 10 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.

耦合模型比对项目第六阶段（Coupled Model Intercomparison Project Phase 6，CMIP6）数据集：本数据集涵盖所有针对「CMIP6.HighResMIP.NCAR.CESM1-CAM5-SE-HR.control-1950」发布的数据集，其完整数据参考语法遵循模板`mip_era.activity_id.institution_id.source_id.experiment_id.member_id.table_id.variable_id.grid_label.version`。

采用社区地球系统模型（Community Earth System Model，CESM）1.3 CAM5谱元配置、耦合CMIP5强迫场的高分辨率气候模型于2012年发布，该模型包含以下组分：气溶胶模块：MAM3（与大气模块网格一致）；大气模块：CAM5.2（0.25度谱元网格，包含777602个网格单元、30层大气结构，顶层气压为2.25毫巴）；大气化学模块：MAM3（与大气模块网格一致）；陆面模块：CLM4（与大气模块网格一致）；海洋模块：POP2（经纬度分辨率为3600×2400，包含62层结构，顶层网格单元水深范围为0~10米）；海洋生物地球化学模块：BEC（与海洋模块网格一致）；海冰模块：CICE4（与海洋模块网格一致）。

该模型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，实验室地址为美国科罗拉多州博尔德市塔布莱梅萨大道1850号，邮编80305。其原生标称分辨率如下：气溶胶模块25千米，大气模块25千米，大气化学模块25千米，陆面模块25千米，海洋模块10千米，海洋生物地球化学模块10千米，海冰模块10千米。

本数据集作为国际协作项目耦合模型比对项目第六阶段（CMIP6）的产出成果（详见《Geoscientific Model Development》特刊：http://www.geosci-model-dev.net/special_issue590.html）。该模拟数据可为解答基础科学问题的气候研究提供支撑，同时可作为政府间气候变化专门委员会第六次评估报告（IPCC-AR6）作者的参考资源。

CMIP6由耦合建模工作组（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统筹。第六阶段依托此前由气候模型诊断与比对计划（Program for Climate Model Diagnosis and Intercomparison，PCMDI）主导开展的前序阶段工作，并通过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）及众多相关协作活动完成实施。原始数据存储于联邦数据节点集群并进行部分复制，IPCC所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）进行长期保存归档。

该项目汇聚了全球约120个全球气候模型与近45家科研机构及组织的模拟成果。- 项目官网：https://pcmdi.llnl.gov/CMIP6。
