ACCESS1-3 model output prepared for CMIP5 piControl, 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: piControl 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. 3.1 piControl (3.1 Pre-Industrial Control) - Version 1: Pre-Industrial coupled atmosphere/ocean control run. Imposes non-evolving pre-industrial conditions.

项目：政府间气候变化专门委员会第五次评估报告（Intergovernmental Panel on Climate Change Assessment Report 5, IPCC-AR5）与耦合模式比较计划数据集——本数据集分属两个项目：1）国际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）第五次耦合模式比较计划（Coupled Model Intercomparison Project Phase 5, CMIP5）。

第五次耦合模式比较计划（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。全球约20家科研机构的近30个气候模式所产生的模拟试验数据，大部分在世界气候数据中心（World Data Centre for Climate, WDCC）、英国大气数据中心（British Atmospheric Data Centre, BADC）以及PCMDI的三个数据节点间完成了同步复制。

概述：piControl（工业化前控制试验）是第五次耦合模式比较计划（CMIP5）的标准试验之一（详见https://pcmdi.llnl.gov/mips/cmip5）。CMIP5旨在为未来五年的协同气候变化试验提供统一框架，其覆盖范围既包含用于IPCC-AR5评估的模拟试验，也包含超出AR5评估范畴的其他模拟试验。

3.1 工业化前控制试验（piControl）- 版本1：耦合大气-海洋系统的工业化前控制运行试验，施加恒定不变的工业化前气候边界条件。试验设计规范详见：https://pcmdi.llnl.gov/mips/cmip5/experiment_design.html

输出变量清单详见：https://pcmdi.llnl.gov/mips/cmip5/datadescription.html

输出数据：以网络通用数据格式（netCDF）存储，按变量分类的时间序列数据，其空间分辨率与对应模式的网格分辨率保持一致。
