IPCC Assessment Report Four ECHAM5/MPIOM data sets

The project embraces the simulations with the coupled climate model ECHAM5/MPIOM, relevant for the 4th Assessment Report (AR4, http://www.ipcc.ch/ipccreports/assessments-reports.htm ) of the Intergovernmental Panel on Climate Change (IPCC). The IPCC has been established by WMO and UNEP to assess scientific, technical and socio-economic information, relevant for the understanding of climate change, its potential impacts and options for adaptation and mitigation. A more detailed description about the work of the IPCC can be found at the IPCC homepage ( http://www.ipcc.ch ) and at ( www.grida.no/climate/ipcc ).
As a further development the Special Report on Emission Scenarios (SRES, http://www.grida.no/Climate/ipcc/emission/) have been constructed, to describe (potential) future developments in the global environment with special reference to the production of greenhouse gases and to aerosol precursor emissions.
A set of four scenario families (A1, A2, B1, B2) have been developed (see also http://www.grida.no/climate/ipcc/emission/index.htm )
The model output data are available at the World Data Center for Climate, Hamburg.( wdc-climate.de ).Projection of future trends based on selected emission scenarios are provided through this project for a great many model variables of ECHAM5/MPIOM . For a selected set of variables the IDCC-Data Distribution Center provides additional data sets from a multitude of models that contribute to the IPCC-AR4 report (project: IPCC_DDC_AR4).

本课题采纳了耦合气候模型ECHAM5/MPIOM的模拟研究，该模型与政府间气候变化专门委员会（IPCC）第四次评估报告（AR4，http://www.ipcc.ch/ipccreports/assessments-reports.htm）相关。IPCC由世界气象组织（WMO）和联合国环境规划署（UNEP）设立，旨在评估与气候变化理解、潜在影响及适应与缓解方案相关的科学、技术和社会经济信息。关于IPCC工作的更详细信息，可在IPCC官方网站（http://www.ipcc.ch）及格雷达网站（www.grida.no/climate/ipcc）查阅。为进一步发展，特别报告关于排放情景（SRES，http://www.grida.no/Climate/ipcc/emission/）已被构建，以描述全球环境（特别是温室气体和气溶胶前体排放）的（潜在）未来发展趋势。已开发了四组情景系列（A1、A2、B1、B2）（详见http://www.grida.no/climate/ipcc/emission/index.htm）。模型输出数据可在汉堡世界气候数据中心（wdc-climate.de）获取。本课题基于选定的排放情景，为ECHAM5/MPIOM的大量模型变量提供了未来趋势的预测。对于选定的一组变量，IDCC数据分发中心（Data Distribution Center）提供了来自众多模型的数据集，这些数据集有助于IPCC-AR4报告（项目：IPCC_DDC_AR4）。
