Project: IPCC Data Distribution Centre : Assessment Report Five data sets - The Intergovernmental Panel on Climate Change (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 option for adaption and migration. Projection of future trends for a number of key variables are provided through this section of the DDC (http://www.ipcc-data.org/sim/gcm_monthly/AR5/ ). Based on the interests and needs of model developers and data users, global scenarios for two time periods where developed: - near-term scenarios that cover the period to about 2035; and - long-term scenarios that cover the period to 2100 and, in a more stylized way, the period to 2300. Four RCPs (Representative Concentration Pathways: RCP2.6, RCP4.5, RCP6.0 and RCP8.5) were constructed from long-term scenarios available in the published literature. These scenarios include time paths for emissions and concentrations of the full suite of greenhouse gases and aerosols and chemically active gases, as well as land use/land cover. They describe alternative technological, socioeconomic, and policy futures including both reference (without explicit climate policy intervention) and climate policy scenarios. The data represent a subset of data sets from the distributed CMIP5 (Coupled Model Intercomparison Project Phase 5) data archive: http://cmip-pcmdi.llnl.gov/cmip5, which was collected by the ETH Zurich in support of the IPCC WG 1 authors. Data are available in NetCDF/CF format (http://cf-pcmdi.llnl.gov/). Fifth Assessment Report of the IPCC: IPCC, 2013: Climate Change 2013: The Physical Science Basis. Contribution of Working Group I to the Fifth Assessment Report of the Intergovernmental Panel on Climate Change [Stocker, T.F., D. Qin, G.-K. Plattner, M. Tignor, S.K. Allen, J. Boschung, A.

Summary: For groups that do not have the capability to download IPCC AR5 data directly from the Data Distribution Center of the IPCC, a data subset was made available on USB flash drive media. The data is a subset of the IPCC Working Group I AR5 snapshot of the 15th March 2013 (the cutoff date for literature to be included in the WGI AR5 report; http://www.ipcc-data.org/sim/gcm_monthly/AR5/WG1-Archive.html ). This AR5 data includes only selected scenarios, the core variables, and to a single run per model of the IPCC Working Group I AR5 snapshot. Included CMIP5 experiments are rcp26, rcp45, rcp85, and historical. Data is prepared for 9 regions. The data is in monthly temporal resolution and the format is NetCDF. For more details on the selected data subset and the data organization please read the attached additional information document.
