AR4 GCM data

To obtain data choose a centre and an scenario there. Then decide which variables you need and which data format you prefer. Finally, you will be guided to the database interface which will let you retrieve the data files one by one .

The list of requested variables can be find here

These data represent a subset of the IPCC-Mode Ouput archive run by PCMDI. There you may also find the complete set of variables in monthly, daily or 3 hourly temporal resolution.

The data formats available are GRIB (machine independent, selfdescriptive binary format, WMO standard) and GZIP (compressed ASCII format). Information on both formats and the internal data structure is given here.

Order Data on DVD
    You can get data from IPCC AR4 scenario runs on DVDs too. For more details see here

Available SRES Scenarion Runs for AR4

 
Status of data : August 2006
For correction and replacement of data sets please look at the errata page of PCMDI
 Please note
The IPCC-DDC data archive contains data sets that have beem stored at the IPCC Model Output Archive at PCMDI after September 1. 2006 . Thus these data may not have contributed to the results of the IPCC - Fourth Assessment Report (AR4). This concernes individual data sets or even complete experiments.
Experiments that contain data sets which became available from the PCMDI archive after 1. September 2006 and do not have an intetrnal information about a processing data prior to 1. September 2006 are marked by a blue colored cell box. Please have a look into the Quality (meta-data) information for more details.
