ACCESS-ESM1.5 model output prepared for CMIP6 'PMIP'

Coupled Model Intercomparison Project Phase 6 (CMIP6) data sets.\nThese data includes all datasets published for 'CMIP6.PMIP.CSIRO.ACCESS-ESM1-5' according to the Data Reference Syntax defined as 'mip_era.activity_id.institution_id.source_id.experiment_id.member_id.table_id.variable_id.grid_label.version'.\nExperiments include the lig127k and midHolocene simulations.\n\nThese 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 are being used by authors of the Sixth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC-AR6).\n\nCMIP6 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 at 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 World Data Centre for Climate (WDCC) at DKRZ.\n\nLineage: The model used in climate research named Australian Community Climate and Earth System Simulator Earth System Model Version 1.5, released in 2019, includes the components:\naerosol: CLASSIC (v1.0), atmos: HadGAM2 (r1.1, N96; 192 x 145 longitude/latitude; 38 levels; top level 39255 m), land: CABLE2.4, ocean: ACCESS-OM2 (MOM5, tripolar primarily 1deg; 360 x 300 longitude/latitude; 50 levels; top grid cell 0-10 m), ocnBgchem: WOMBAT (same grid as ocean), seaIce: CICE4.1 (same grid as ocean).\nThe model was run by the Commonwealth Scientific and Industrial Research Organisation, Aspendale, Victoria 3195, Australia (CSIRO) in native nominal resolutions: aerosol: 250 km, atmos: 250 km, land: 250 km, ocean: 100 km, ocnBgchem: 100 km, seaIce: 100 km.

耦合模式比较计划第六阶段（Coupled Model Intercomparison Project Phase 6，CMIP6）数据集。本数据集涵盖依据`mip_era.activity_id.institution_id.source_id.experiment_id.member_id.table_id.variable_id.grid_label.version`定义的数据参考语法（Data Reference Syntax）发布的全部`CMIP6.PMIP.CSIRO.ACCESS-ESM1-5`类数据集。相关试验包含末次间冰期（lig127k）与全新世中期（midHolocene）模拟试验。

本数据集作为国际协调的耦合模式比较计划第六阶段（CMIP6）的一部分生成（详见《地球科学模型开发（Geoscientific Model Development，GMD）》特刊：http://www.geosci-model-dev.net/special_issue590.html）。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，同时已被政府间气候变化专门委员会（Intergovernmental Panel on Climate Change，IPCC）第六次评估报告（IPCC-AR6）的撰稿人所采用。

CMIP6由耦合模式工作组（Working Group on Coupled Modelling，WGCM）协调，作为世界气候研究计划（World Climate Research Programme，WCRP）的一部分实施。第六阶段依托此前在气候模式诊断与比较计划（Program for Climate Model Diagnosis and Intercomparison，PCMDI）主导下完成的前序阶段工作，其实施依赖地球系统网格联合会（Earth System Grid Federation，ESGF）、环境数据分析中心（Centre for Environmental Data Analysis，CEDA）以及众多相关配套活动。原始数据存储于分布式数据节点集群并进行部分复制，而IPCC所依赖的绝大多数数据正被归档至由德国气候计算中心（DKRZ）托管的世界气候数据中心（World Data Centre for Climate，WDCC）运营的IPCC数据分发中心（IPCC Data Distribution Centre，IPCC DDC），以实现长期保存。

模型溯源：本研究采用的模式为2019年发布的澳大利亚社区气候与地球系统模拟器地球系统模式版本1.5（Australian Community Climate and Earth System Simulator Earth System Model Version 1.5，ACCESS-ESM1-5），其组成模块如下：气溶胶模块：CLASSIC（v1.0），大气模块：HadGAM2（r1.1，N96；192×145经纬度格点；38层，模式顶高度39255米），陆面模块：CABLE2.4，海洋模块：ACCESS-OM2（MOM5，主要为1°分辨率三极网格；360×300经纬度格点；50层，顶层网格深度0-10米），海洋生物地球化学模块：WOMBAT（与海洋模块网格一致），海冰模块：CICE4.1（与海洋模块网格一致）。该模式由澳大利亚维多利亚州阿斯彭代尔（邮编3195）的澳大利亚联邦科学与工业研究组织（Commonwealth Scientific and Industrial Research Organisation，CSIRO）运行，其各模块固有标称分辨率为：气溶胶模块250千米，大气模块250千米，陆面模块250千米，海洋模块100千米，海洋生物地球化学模块100千米，海冰模块100千米。
