IPCC DDC: IPSL IPSL-CM6A-LR model output prepared for CMIP6 DAMIP hist-GHG

Project: Coupled Model Intercomparison Project Phase 6 (CMIP6) datasets - 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. Summary: These data include the subset used by IPCC AR6 WGI authors of the datasets originally published in ESGF for 'CMIP6.DAMIP.IPSL.IPSL-CM6A-LR.hist-GHG' 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.

项目：耦合模式比较计划第六阶段（Coupled Model Intercomparison Project Phase 6, CMIP6）数据集——本数据集为国际协调推进的耦合模式比较计划第六阶段（CMIP6；详见《地理科学模型开发》特刊：http://www.geosci-model-dev.net/special_issue590.html）的产出数据。模拟数据可为解答核心科学问题的气候研究提供支撑，同时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）的作者提供研究资源。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）协调实施。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）主导的前几阶段工作，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）及众多相关协作项目完成落地。原始数据存储于分布式数据节点集群并实现部分复制，IPCC引用的多数数据已交由德国气候计算中心（Deutsches Klimarechenzentrum, 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。该项目汇集了全球约120个全球气候模式及45家科研机构与组织的模拟实验数据。

数据集概述：本数据集包含IPCC AR6第一工作组作者所使用的原始数据集子集，该子集最初发布于ESGF平台，对应实验标识为`CMIP6.DAMIP.IPSL.IPSL-CM6A-LR.hist-GHG`，其数据引用语法遵循模板：`mip_era.activity_id.institution_id.source_id.experiment_id.member_id.table_id.variable_id.grid_label.version`。
