Model output for IPCC Fourth Assessment experiment. These data represent monthly averaged values of selected variables for the Data Distribution Centre (DDC) of the Intergovernmental Panel on Climate Change (IPCC). (see also https://www.ipcc-data.org) For specific scenario details see experiment summery. These data are in GRIB format. They are also available in netCDF format.
These data are added to the IPCC AR4 Archive at PCMDI (https://esg.llnl.gov:8443/home/publicHomePage.do) after August 31. 2006 Hence it is not sure if these data are still included into the calculations for the IPCC AR4 .
