IPSL IPSL-CM6A-LR model output prepared for CMIP6 CMIP abrupt-4xCO2

Coupled Model Intercomparison Project Phase 6 (CMIP6) datasets: These data include all datasets published for 'CMIP6.CMIP.IPSL.IPSL-CM6A-LR.abrupt-4xCO2' 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 IPSL-CM6A-LR climate model, released in 2017, includes the following components:
atmos: LMDZ (NPv6, N96; 144 x 143 longitude/latitude; 79 levels; top level 80000 m), land: ORCHIDEE (v2.0, Water/Carbon/Energy mode), ocean: NEMO-OPA (eORCA1.3, tripolar primarily 1deg; 362 x 332 longitude/latitude; 75 levels; top grid cell 0-2 m), ocnBgchem: NEMO-PISCES, seaIce: NEMO-LIM3.
The model was run by the Institut Pierre Simon Laplace, Paris 75252, France (IPSL) in native nominal resolutions: atmos: 250 km, land: 250 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：这些数据包含所有以“CMIP6.CMIP.IPSL.IPSL-CM6A-LR.abrupt-4xCO2”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”。

IPSL-CM6A-LR气候模式于2017年发布，包含以下组件：大气（atmos）：LMDZ（NPv6版本，N96分辨率；经纬度144×143；79层；顶层高度80000米）、陆地（land）：ORCHIDEE（2.0版本，水/碳/能量模式）、海洋（ocean）：NEMO-OPA（eORCA1.3配置，主为1度三极网格；经纬度362×332；75层；顶层网格单元0-2米）、海洋生物地球化学（ocnBgchem）：NEMO-PISCES、海冰（seaIce）：NEMO-LIM3。该模式由法国巴黎75252的皮埃尔·西蒙·拉普拉斯研究所（Institut Pierre Simon Laplace，IPSL）以原生标称分辨率运行：大气250千米、陆地250千米、海洋100千米、海洋生物地球化学100千米、海冰100千米。

项目背景：这些数据是国际协调的耦合模式比较计划第六阶段（CMIP6）的一部分（另见《地球科学模型开发》（Geoscientific Model Development，GMD）特刊：http://www.geosci-model-dev.net/special_issue590.html）。模拟数据为旨在解答基础科学问题的气候研究提供了基础，并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（AR6）作者的资源。

CMIP6是由耦合建模工作组（Working Group on Coupled Modelling，WGCM）协调的项目，隶属于世界气候研究计划（World Climate Research Programme，WCRP）。第六阶段基于气候模式诊断与比较计划（Program for Climate Model Diagnosis and Intercomparison，PCMDI）主导执行的前几阶段，依赖地球系统网格联盟（Earth System Grid Federation，ESGF）、环境数据分析中心（Centre for Environmental Data Analysis，CEDA）及众多相关活动予以实施。原始数据托管并部分复制于联邦数据节点集合，IPCC所依赖的大部分数据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）进行长期保存归档。

该项目包含来自全球约120个全球气候模式及45家机构与组织的模拟结果。——项目网站：https://pcmdi.llnl.gov/CMIP6。
