IPCC-AR6_CMIP6 Regional Subset Africa

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 a subset of the CMIP6 input data assessed by the IPCC AR6 WGI authors for region Africa (35°W – 72°E, 58°S – 40°N). Included are 12 core variables (orog, sftlf, sftgif, psl, tas, tasmin, tasmax, uas, vas, huss, pr, rsds) of the experiments historical, ssp126, ssp245, ssp370, and ssp585 for models providing more than 5 of these variables.

项目：耦合模型比较计划第六阶段（Coupled Model Intercomparison Project Phase 6, CMIP6）数据集——本数据集为国际协调推进的耦合模型比较计划第六阶段（CMIP6；详见《Geoscientific Model Development》特刊：http://www.geosci-model-dev.net/special_issue590.html）的产出数据。该模拟数据为解答核心科学问题的气候研究提供了基础支撑，同时也为政府间气候变化专门委员会第六次评估报告（IPCC-AR6）的作者团队提供了核心数据资源。
CMIP6由耦合建模工作组（Working Group on Coupled Modelling, WGCM）在世界气候研究计划（World Climate Research Programme, WCRP）框架下协调开展。本阶段承袭了此前由气候模型诊断与比较计划（Program for Climate Model Diagnosis and Intercomparison, PCMDI）主导的多轮前期研究，依托地球系统网格联盟（Earth System Grid Federation, ESGF）与环境数据分析中心（Centre for Environmental Data Analysis, CEDA），并联合多项相关活动完成项目实施。原始数据存储于分布式数据节点集群中并实现部分副本复制，IPCC所依赖的绝大多数数据将由德国气候计算中心（German Climate Computing Center, DKRZ）托管的IPCC数据分发中心（IPCC Data Distribution Centre, IPCC DDC）进行长期归档保存。
该项目涵盖了全球约120个全球气候模式以及近45家科研机构与组织的模拟试验数据。
数据集概览：本数据集包含IPCC AR6第一工作组作者针对非洲区域（35°W – 72°E，58°S – 40°N）评估遴选的CMIP6输入数据子集。针对提供至少5个上述核心变量的气候模式，纳入了历史试验、ssp126、ssp245、ssp370及ssp585情景下的12个核心变量（orog、sftlf、sftgif、psl、tas、tasmin、tasmax、uas、vas、huss、pr、rsds）。
