IPCC DDC: UA MCM-UA-1-0 model output prepared for CMIP6 ScenarioMIP

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.ScenarioMIP.UA.MCM-UA-1-0' 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 Manabe Climate Model v1.0 - University of Arizona climate model, released in 1991, includes the following components: aerosol: Modifies surface albedoes (Haywood et al. 1997, doi: 10.1175/1520-0442(1997)010<1562:GCMCOT>2.0.CO;2), atmos: R30L14 (3.75 X 2.5 degree (long-lat) configuration; 96 x 80 longitude/latitude; 14 levels; top level 0.015 sigma, 15 mb), land: Standard Manabe bucket hydrology scheme (Manabe 1969, doi: 10.1175/1520-0493(1969)097<0739:CATOC>2.3.CO;2), landIce: Specified location - invariant in time, has high albedo and latent heat capacity, ocean: MOM1.0 (MOM1, 1.875 X 2.5 deg; 192 x 80 longitude/latitude; 18 levels; top grid cell 0-40 m), seaIce: Thermodynamic ice model (free drift dynamics). The model was run by the Department of Geosciences, University of Arizona, Tucson, AZ 85721, USA (UA) in native nominal resolutions: aerosol: 250 km, atmos: 250 km, land: 250 km, landIce: 250 km, ocean: 250 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
本批数据为国际协调推进的耦合模式比较计划第六阶段（CMIP6；详见《Geoscientific Model Development》特刊：http://www.geosci-model-dev.net/special_issue590.html）的产出成果。其模拟数据为解答核心科学问题的气候研究提供了支撑，同时作为政府间气候变化专门委员会第六次评估报告（Intergovernmental Panel on Climate Change Sixth Assessment Report, IPCC-AR6）作者群体的核心资源。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）协调统筹。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）主导的前期项目，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）及众多配套协作活动完成落地实施。原始数据存储于分布式数据节点集群并实现部分副本共享，IPCC所依赖的多数数据集将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）开展长期归档保存。本项目汇聚了全球约120个全球气候模式与45家科研机构及组织的模拟成果。

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地球系统网格联盟（ESGF）发布数据集的子集，对应标识为`CMIP6.ScenarioMIP.UA.MCM-UA-1-0`，其数据参考语法遵循模板：`mip_era.activity_id.institution_id.source_id.experiment_id.member_id.table_id.variable_id.grid_label.version`。

Manabe气候模式v1.0（Manabe Climate Model v1.0）——亚利桑那大学气候模式，于1991年正式发布，包含以下组成模块：
1. 气溶胶模块：用于修正地表反照率（Haywood等，1997，doi: 10.1175/1520-0442(1997)010<1562:GCMCOT>2.0.CO;2）
2. 大气模块：采用R30L14配置（经纬度分辨率3.75°×2.5°，经度×纬度格点数为96×80，共14层垂直结构，顶层为0.015 sigma坐标，对应15 mb气压）
3. 陆面模块：采用标准Manabe桶式水文方案（Manabe，1969，doi: 10.1175/1520-0493(1969)097<0739:CATOC>2.3.CO;2）
4. 陆冰模块：时空位置固定不变，具备高反照率与潜热容量
5. 海洋模块：采用MOM1.0模式（MOM1，分辨率1.875°×2.5°，经度×纬度格点数为192×80，共18层垂直结构，顶层网格水深范围0~40 m）
6. 海冰模块：热力学海冰模式，包含自由漂移动力学过程
