Advanced Dataset Search Documentation Added

The easiest way to find the files you’re looking for is to use the CMIP5 Community Storage Server – Advanced Dataset Search page. This page provides free-text and faceted search functionality of all available data files and a dynamic, paginated result table. FTP and HTTP links to the data files are provided in the result table to allow users to download files of interest directly from the search page. Additionally, the result set – including paths and file names – may be downloaded in a variety of different formats including CSV, JSON, PHP, Python, and XML.

For more information on how to use the search page, see the Advanced Dataset Search: User Manual.

Downloads Temporarily Halted!

CMIP5 dataset downloads are temporarily halted as the wget scripts are failing to retrieve ESGF certificates used to verify the identity of the host data nodes. These certificates expire and must be refreshed periodically, which requires that I manually provide the login credentials for my openID. However, the server hosting my openID ( is down, and consequently the certificates cannot be retrieved.

Hopefully, this a temporary issue. I will continue to check the status of the openID provider periodically.


UPDATE (10/29 08:35): Other data nodes are still up (e.g. DKRZ), but the MyProxyLogon is redirected to (which is down) from each data node.

UPDATE (10/30 17:45): The error causing the wget scripts to fail is shown below.
