BCC BCC-CSM2MR model output prepared for CMIP6 ScenarioMIP

Coupled Model Intercomparison Project Phase 6 (CMIP6) datasets: These data include all datasets published for 'CMIP6.ScenarioMIP.BCC.BCC-CSM2-MR' 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.

耦合模型相互比较计划第六阶段（Coupled Model Intercomparison Project Phase 6, CMIP6）数据集：本数据集涵盖所有以`mip_era.activity_id.institution_id.source_id.experiment_id.member_id.table_id.variable_id.grid_label.version`为完整数据参考语法（Data Reference Syntax）模板发布的、针对`CMIP6.ScenarioMIP.BCC.BCC-CSM2-MR`的数据集。

BCC-CSM2-MR气候模型于2017年正式发布，其组成模块如下：大气模块为BCC_AGCM3_MR（分辨率T106；经纬度网格尺寸为320×160；垂直分层共46层；顶层气压为1.46 hPa）；陆面模块为BCC_AVIM2；海洋模块为MOM4（经纬度分辨率设置：10°S至10°N区域为1/3°，10°N至30°N、10°S至30°S区域为1/3°至1°，高纬度区域为1°；经纬度网格尺寸为360×232；垂直分层共40层；顶层网格水深范围为0-10 m）；海冰模块为SIS2。

该模型由位于中国北京100081的北京气候中心（Beijing Climate Center, BCC）以标称原生分辨率运行：大气模块分辨率为100 km，陆面模块为100 km，海洋模块为50 km，海冰模块为50 km。

项目背景：本数据集作为国际协作推进的耦合模型相互比较计划第六阶段（CMIP6；详见《Geoscientific Model Development》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核心科学问题的气候研究提供基础支撑，同时可作为政府间气候变化专门委员会第六次评估报告（Intergovernmental Panel on Climate Change Sixth Assessment Report, IPCC-AR6）作者的参考资源。

CMIP6由世界气候研究计划（World Climate Research Programme, WCRP）下属的耦合建模工作组（Working Group on Coupled Modelling, WGCM）协调统筹。第六阶段继承了此前由气候模型诊断与相互比较计划（Program for Climate Model Diagnosis and Intercomparison, PCMDI）主导的前序阶段成果，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）及众多相关协作活动完成落地实施。原始数据存储于分布式数据节点集群并进行部分副本备份，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）开展长期归档保存。

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