The EC Earth 3.3 climate model, released in 2019, includes the following components:
atmos: IFS cy36r4 (TL255, linearly reduced Gaussian grid equivalent to 512 x 256 longitude/latitude; 91 levels; top level 0.01 hPa), land: HTESSEL (land surface scheme built in IFS), ocean: NEMO3.6 (ORCA1 tripolar primarily 1 deg with meridional refinement down to 1/3 degree in the tropics; 362 x 292 longitude/latitude; 75 levels; top grid cell 0-1 m), seaIce: LIM3.
The model was run by the AEMET, Spain; BSC, Spain; CNR-ISAC, Italy; DMI, Denmark; ENEA, Italy; FMI, Finland; Geomar, Germany; ICHEC, Ireland; ICTP, Italy; IDL, Portugal; IMAU, The Netherlands; IPMA, Portugal; KIT, Karlsruhe, Germany; KNMI, The Netherlands; Lund University, Sweden; Met Eireann, Ireland; NLeSC, The Netherlands; NTNU, Norway; Oxford University, UK; surfSARA, The Netherlands; SMHI, Sweden; Stockholm University, Sweden; Unite ASTR, Belgium; University College Dublin, Ireland; University of Bergen, Norway; University of Copenhagen, Denmark; University of Helsinki, Finland; University of Santiago de Compostela, Spain; Uppsala University, Sweden; Utrecht University, The Netherlands; Vrije Universiteit Amsterdam, the Netherlands; Wageningen University, The Netherlands. Mailing address: EC-Earth consortium, Rossby Center, Swedish Meteorological and Hydrological Institute/SMHI, SE-601 76 Norrkoping, Sweden (EC-Earth-Consortium) in native nominal resolutions: atmos: 100 km, land: 100 km, ocean: 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.

耦合模型相互比较项目第六阶段（Coupled Model Intercomparison Project Phase 6，CMIP6）数据集：本数据集涵盖所有以`CMIP6.PMIP.EC-Earth-Consortium.EC-Earth3`标识发布的数据集，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`。

2019年发布的EC-Earth3.3气候模式包含以下组成模块：
大气模块采用IFS cy36r4（TL255格式，线性缩减高斯网格，等效分辨率为512×256经纬度格点；共91层，顶层气压为0.01百帕）；陆面模块采用HTESSEL（集成于IFS的陆面过程方案）；海洋模块采用NEMO3.6（ORCA1三极网格，主分辨率约1°，热带区域经向加密至1/3°；格点尺寸为362×292经纬度；共75层，顶层网格水深范围0~1米）；海冰模块采用LIM3。

该模式由以下机构共同运行：西班牙AEMET、西班牙BSC、意大利CNR-ISAC、丹麦DMI、意大利ENEA、芬兰FMI、德国Geomar、爱尔兰ICHEC、意大利ICTP、葡萄牙IDL、荷兰IMAU、葡萄牙IPMA、德国卡尔斯鲁厄KIT、荷兰KNMI、瑞典隆德大学、爱尔兰Met Eireann、荷兰NLeSC、挪威NTNU、英国牛津大学、荷兰surfSARA、瑞典SMHI、瑞典斯德哥尔摩大学、比利时Unite ASTR、爱尔兰都柏林大学学院、挪威卑尔根大学、丹麦哥本哈根大学、芬兰赫尔辛基大学、西班牙圣地亚哥德孔波斯特拉大学、瑞典乌普萨拉大学、荷兰乌得勒支大学、荷兰阿姆斯特丹自由大学、荷兰瓦赫宁根大学。通讯地址：瑞典气象与水文研究所（SMHI）罗斯比中心EC-Earth联盟，瑞典诺尔雪平SE-601 76（EC-Earth-Consortium）。各模块原生标称分辨率为：大气模块100公里、陆面模块100公里、海洋模块100公里、海冰模块100公里。

项目背景：本数据集作为国际协调的耦合模型相互比较项目第六阶段（CMIP6；详见《地球模式发展》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核心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）作者群体的核心数据资源。

CMIP6由耦合建模工作组（WGCM）作为世界气候研究计划（WCRP）的组成部分协调推进。第六阶段继承了此前在气候模式诊断与相互比较计划（PCMDI）主导下完成的多轮项目成果，依托地球系统网格联盟（ESGF）与环境数据分析中心（CEDA）及众多相关配套活动完成落地。原始数据托管并部分副本存储于联邦化的数据节点集群中，IPCC所依赖的绝大多数数据已交由德国气候计算中心（DKRZ）运营的IPCC数据分发中心（IPCC DDC）进行长期归档保存。

该项目涵盖全球约120个全球气候模式的模拟试验与全球约45家科研机构及组织的参与。项目官网：https://pcmdi.llnl.gov/CMIP6。
