Project: 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).
Summary: The data represent monthly average values of selected variables for the Data Distribution Centre (DDC) of the Intergovermental Panel on Climate Change (IPCC).

The A1B scenario is the part of the A1 family which describes a balance across all energy sources. The experiment has been initialized in year 2000 of the 20C_2 run and continues until year 2100 with anthropogenic forcings (CO2, CH4, N2O, CFCs, O3 and sulfate) according to A1B. The experiment is extended until year 2300 with all concentrations fixed at their levels of year 2100 (stabilization experiment). Datasets with higher resolution (6 hourly) are also available.
Technical data to this experiment:
The experiment is using ECHAM5.2.02a coupled to MPI-OM Vers. 1.0 GR1.5L40 and was run on a NEC-SX (hurrikan). The output from the model run: hurrikan.dkrz.de: /ut/k/k204096/EXP200/run223
