NCAR CESM2-WACCM model output prepared for CMIP6 AerChemMIP piClim-N2O

Coupled Model Intercomparison Project Phase 6 (CMIP6) datasets: These data include all datasets published for 'CMIP6.AerChemMIP.NCAR.CESM2-WACCM.piClim-N2O' 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 CESM2-WACCM climate model, released in 2018, includes the following components:
aerosol: MAM4 (same grid as atmos), atmos: WACCM6 (0.9x1.25 finite volume grid; 288 x 192 longitude/latitude; 70 levels; top level 4.5e-06 mb), atmosChem: MAM4 (same grid as atmos), land: CLM5 (same grid as atmos), landIce: CISM2.1, ocean: POP2 (320 x 384 longitude/latitude; 60 levels; top grid cell 0-10 m), ocnBgchem: MARBL (same grid as ocean), seaIce: CICE5.1 (same grid as ocean).
The model was run by the National Center for Atmospheric Research, Climate and Global Dynamics Laboratory, 1850 Table Mesa Drive, Boulder, CO 80305, USA (NCAR) in native nominal resolutions: aerosol: 100 km, atmos: 100 km, atmosChem: 100 km, land: 100 km, landIce: 5 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（CMIP6）数据集：这些数据包含所有以“CMIP6.AerChemMIP.NCAR.CESM2-WACCM.piClim-N2O”发布的数据集，其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”。

CESM2-WACCM气候模型于2018年发布，包含以下组件：气溶胶（aerosol）：MAM4（与大气网格相同）；大气（atmos）：WACCM6（0.9×1.25有限体积网格；经纬度288×192；70层；顶层4.5e-06毫巴）；大气化学（atmosChem）：MAM4（与大气网格相同）；陆地（land）：CLM5（与大气网格相同）；陆冰（landIce）：CISM2.1；海洋（ocean）：POP2（经纬度320×384；60层；顶层网格单元0-10米）；海洋生物地球化学（ocnBgchem）：MARBL（与海洋网格相同）；海冰（seaIce）：CICE5.1（与海洋网格相同）。

该模型由美国国家大气研究中心气候与全球动力学实验室（NCAR，地址：美国科罗拉多州博尔德市Table Mesa Drive 1850号，邮编80305）以原生标称分辨率运行：气溶胶：100千米；大气：100千米；大气化学：100千米；陆地：100千米；陆冰：5千米；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》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，作为世界气候研究计划（WCRP）的一部分。第六阶段基于此前在气候模型诊断与比较计划（PCMDI）领导下执行的各阶段，并依赖地球系统网格联盟（ESGF）、环境数据分析中心（CEDA）及众多相关活动来实施。原始数据托管并部分复制于联合数据节点集合，IPCC所依赖的大部分数据正由德国气候计算中心（DKRZ）托管的IPCC数据分发中心（IPCC DDC）进行长期保存归档。

该项目包含来自全球约120个全球气候模型（global climate model）及约45家机构与组织的模拟结果。- 项目网站：https://pcmdi.llnl.gov/CMIP6。
