IPCC DDC: NASA-GISS GISS-E2.1G model output prepared for CMIP6 CMIP amip

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.CMIP.NASA-GISS.GISS-E2-1-G.amip' 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 GISS-E2.1G climate model, released in 2019, includes the following components: aerosol: Varies with physics-version (p==1 none, p==3 OMA, p==4 TOMAS, p==5 MATRIX), atmos: GISS-E2.1 (2.5x2 degree; 144 x 90 longitude/latitude; 40 levels; top level 0.1 hPa), atmosChem: Varies with physics-version (p==1 Non-interactive, p>1 GPUCCINI), land: GISS LSM, ocean: GISS Ocean (GO1, 1 degree; 360 x 180 longitude/latitude; 40 levels; top grid cell 0-10 m), seaIce: GISS SI. The model was run by the Goddard Institute for Space Studies, New York, NY 10025, USA (NASA-GISS) in native nominal resolutions: aerosol: 250 km, atmos: 250 km, atmosChem: 250 km, land: 250 km, ocean: 100 km, seaIce: 250 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——本批数据作为国际协调的耦合模式比较计划第六阶段（CMIP6；另见《地理科学模型开发》特刊：http://www.geosci-model-dev.net/special_issue590.html）的组成部分生成。该模拟数据为旨在解答核心科学问题的气候研究提供了支撑基础，同时可作为政府间气候变化专门委员会第六次评估报告（IPCC-AR6）作者的研究资源。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）协调推进。第六阶段延续了此前由气候模式诊断与比较计划（Program for Climate Model Diagnosis and Intercomparison，PCMDI）主导开展的多轮计划，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）及众多配套活动完成项目实施。原始数据托管并部分复制于联邦化数据节点集群中，IPCC所依赖的绝大多数数据将由德国气候计算中心（German Climate Computing Center，DKRZ）运营的IPCC数据分发中心（IPCC Data Distribution Centre，IPCC DDC）进行长期归档保存。本项目汇集了全球约120个全球气候模式与近45家科研机构及组织的模拟试验数据。
摘要：本数据集包含IPCC AR6第一工作组作者所使用的子集数据，该子集源自地球系统网格联盟（ESGF）发布的原始数据集`CMIP6.CMIP.NASA-GISS.GISS-E2-1-G.amip`，完整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`。于2019年发布的GISS-E2.1G气候模式包含以下组成模块：气溶胶模块：随物理版本不同存在差异（p==1时无气溶胶模块，p==3为OMA，p==4为TOMAS，p==5为MATRIX）；大气模块：GISS-E2.1（分辨率为2.5°×2°，经纬度网格为144×90，共40层，顶层气压为0.1 hPa）；大气化学模块：随物理版本不同存在差异（p==1时为非交互式，p>1时为GPUCCINI）；陆面模块：GISS陆面模式（GISS LSM）；海洋模块：GISS海洋模式（GO1，分辨率为1°，经纬度网格为360×180，共40层，顶层网格单元水深范围为0~10 m）；海冰模块：GISS海冰模式（GISS SI）。该模式由美国纽约州纽约市戈达德太空研究所（NASA-GISS）以原生标称分辨率运行，各模块分辨率分别为：气溶胶250 km、大气250 km、大气化学250 km、陆面250 km、海洋100 km、海冰250 km。
