For external users of ISIMIP data, access is granted via the ISIMIP node of the Earth System Grid Federation. The procedure for downloading the data is analogous to downloading official CMIP5 data from other ESGF nodes.
Please read the terms of use carefully, and only proceed if you agree. Please also pay attention to our overview data changes and caveats (for Fast Track). More detailed help can be found in the official Earth System CoG web user tutorials.
Note: We are in the process of migrating our data from the ESGF portal to the new ISIMIP repository, a service hosted by the PIK. Please give it a try, your feedback is important for us!
