ACCESS1-3 model output prepared for CMIP5 abrupt4xCO2 (Version 2015), served by ESGF

Project: IPCC Assessment Report 5 and Coupled Model Intercomparison Project data sets - These data belong to two projects: 1) to the Assessment Report No 5 of the International Panel on Climate Change (IPCC-AR5) and 2) to the Coupled Model Intercomparison Project No 5 (CMIP5). CMIP5 is executed by the Program for Climate Model Diagnosis and Intercomparison (PCMDI) on behalf of the World Climate Research Programme (WCRP). Most of the data is replicated between the three data nodes at the World Data Centre for Climate (WDCC), the British Atmospheric Data Centre (BADC), and the PCMDI. The project embraces the simulations with about 30 climate models of about 20 institutes worldwide. Summary: The experiment includes the latest CMIP5 data of CSIRO for January 2015. The data is a newer version of the IPCC DDC AR5 data of CSIRO. 'abrupt4xco2' is an experiment of the CMIP5 - Coupled Model Intercomparison Project Phase 5 (https://pcmdi.llnl.gov/mips/cmip5). CMIP5 is meant to provide a framework for coordinated climate change experiments for the next five years and thus includes simulations for assessment in the AR5 as well as others that extend beyond the AR5. 6.3 abrupt4xco2 (6.3 Abrupt 4XCO2) - Version 1: Impose an instantaneous quadrupling of CO2, then hold fixed.

项目：IPCC第五次评估报告与耦合模式比较计划数据集——本数据集分属两个项目：1）联合国政府间气候变化专门委员会（Intergovernmental Panel on Climate Change，IPCC）第五次评估报告（IPCC-AR5）；2）耦合模式比较计划第五阶段（Coupled Model Intercomparison Project Phase 5，CMIP5）。CMIP5由气候模式诊断与比较计划（Program for Climate Model Diagnosis and Intercomparison，PCMDI）代表世界气候研究计划（World Climate Research Programme，WCRP）牵头实施。全球范围内世界气候数据中心（World Data Centre for Climate，WDCC）、英国大气数据中心（British Atmospheric Data Centre，BADC）与PCMDI的三个数据节点间存有大部分数据的副本。本项目涵盖了全球约20家科研机构的约30个气候模式的模拟试验。

摘要：本试验包含2015年1月发布的澳大利亚联邦科学与工业研究组织（Commonwealth Scientific and Industrial Research Organisation，CSIRO）最新CMIP5数据，该数据为CSIRO旗下IPCC数据分发中心发布的IPCC-AR5数据的更新版本。“abrupt4xco2”为CMIP5（耦合模式比较计划第五阶段，https://pcmdi.llnl.gov/mips/cmip5）的一项标准试验。CMIP5旨在为未来五年的协同气候变化试验提供统一框架，其模拟试验既包含用于IPCC-AR5评估的内容，也涵盖超出该评估范围的其他试验。

6.3 abrupt4xco2（6.3 瞬时4倍CO₂试验）版本1：试验方案为瞬时将大气CO₂浓度提升至初始值的4倍并保持恒定。试验设计详情参见：https://pcmdi.llnl.gov/mips/cmip5/experiment_design.html。输出变量列表参见：https://pcmdi.llnl.gov/mips/cmip5/datadescription.html。输出内容为各变量的时间序列，采用模式网格空间分辨率，格式为网络通用数据格式（netCDF）。
