BCC BCC-CSM2MR model output prepared for CMIP6 LS3MIP land-hist-princeton

Coupled Model Intercomparison Project Phase 6 (CMIP6) datasets: These data include all datasets published for 'CMIP6.LS3MIP.BCC.BCC-CSM2-MR.land-hist-princeton' 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 BCC-CSM 2 MR climate model, released in 2017, includes the following components:
atmos: BCC_AGCM3_MR (T106; 320 x 160 longitude/latitude; 46 levels; top level 1.46 hPa), land: BCC_AVIM2, ocean: MOM4 (1/3 deg 10S-10N, 1/3-1 deg 10-30 N/S, and 1 deg in high latitudes; 360 x 232 longitude/latitude; 40 levels; top grid cell 0-10 m), seaIce: SIS2.
The model was run by the Beijing Climate Center, Beijing 100081, China (BCC) in native nominal resolutions: atmos: 100 km, land: 100 km, ocean: 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：本数据集涵盖所有遵循"mip_era.activity_id.institution_id.source_id.experiment_id.member_id.table_id.variable_id.grid_label.version"完整数据引用语法模板发布的"CMIP6.LS3MIP.BCC.BCC-CSM2-MR.land-hist-princeton"相关数据集。

2017年发布的BCC-CSM2-MR气候模式包含以下分量模块：大气模块：BCC_AGCM3_MR（分辨率T106，经纬度网格320×160，共46层，顶层气压1.46 hPa）；陆面模块：BCC_AVIM2；海洋模块：MOM4（10°S-10°N区域分辨率为1/3°，10°-30°N/S区域分辨率为1/3°-1°，高纬度区域分辨率为1°；经纬度网格360×232，共40层，顶层网格单元水深0-10 m）；海冰模块：SIS2。

该模式由中国北京100081的北京气候中心（Beijing Climate Center, BCC）以原始标称分辨率运行：大气模块100 km，陆面模块100 km，海洋模块50 km，海冰模块50 km。

项目背景：本数据集作为国际协调开展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，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）作者群体的参考资源。

耦合模式比较计划第六阶段（CMIP6）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）协调推进。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）主导开展的多轮对比实验，并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）及众多相关协作活动完成落地。原始数据存储于分布式数据节点集群并实现部分复制，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）进行长期保存。

该项目汇聚了全球约120个全球气候模式与约45家科研机构及组织的模拟实验。——项目官网：https://pcmdi.llnl.gov/CMIP6。
