NASA-GISS GISS-E2.1G model output prepared for CMIP6 AerChemMIP piClim-NH3

Coupled Model Intercomparison Project Phase 6 (CMIP6) datasets: These data include all datasets published for 'CMIP6.AerChemMIP.NASA-GISS.GISS-E2-1-G.piClim-NH3' 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.

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（CMIP6）数据集：这些数据包含所有以‘CMIP6.AerChemMIP.NASA-GISS.GISS-E2-1-G.piClim-NH3’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’。

GISS-E2.1G气候模型于2019年发布，包含以下组件：气溶胶（aerosol）：随物理版本变化（p==1时无，p==3时为OMA，p==4时为TOMAS，p==5时为MATRIX）；大气（atmos）：GISS-E2.1（分辨率2.5×2度；经纬度144×90；40层；顶层0.1百帕）；大气化学（atmosChem）：随物理版本变化（p==1时为非交互式，p>1时为GPUCCINI）；陆面：GISS LSM；海洋：GISS Ocean（GO1，分辨率1度；经纬度360×180；40层；顶层网格单元0-10米）；海冰：GISS SI。

该模型由美国纽约州纽约市10025号的戈达德太空研究所（NASA-GISS）以原生标称分辨率运行：气溶胶：250千米；大气：250千米；大气化学：250千米；陆面：250千米；海洋：100千米；海冰：250千米。

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；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）的一部分。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第六次评估报告（IPCC-AR6）作者的资源。

CMIP6是由耦合模式工作组（WGCM）协调的项目，隶属于世界气候研究计划（WCRP）。第六阶段基于气候模型诊断与比较计划（PCMDI）领导下执行的前几阶段，并依赖地球系统网格联盟（ESGF）、环境数据分析中心（CEDA）以及众多相关活动来实施。原始数据托管在联合数据节点集合上并部分复制，IPCC依赖的大部分数据正由德国气候计算中心（DKRZ）托管的IPCC数据分发中心（IPCC DDC）进行长期保存。

该项目包含来自全球约120个全球气候模型和45个机构及组织的模拟结果。- 项目网站：https://pcmdi.llnl.gov/CMIP6。
