GL: That's difficult and also depends on the RCMs. I propose to at least indicate into the table of variable the one we "try" to provide for each domain (basically one additional column per domain).
ANDRAS: I thought the non-European domains will use the same set of variables, is that a wrong assumption?
The CDS subset of CORDEX data have been through a metadata quality control procedure which ensures a high standard of reliability of the data. It may be for example that similar data can be found in the main CORDEX archive at the ESGF (Earth System Grid Federation) however these data come with no quality assurance and may have metadata errors or omissions. The quality-control process means that the CDS subset of CORDEX data is further reduced to exclude data that have metadata errors or inconsistencies. It is important to note that passing of the quality control should not be confused with validity: for example, it will be possible for a file to have fully compliant metadata but contain gross errors in the data that have not been noted. In other words, it means that the quality control is purely technical and does not contain any scientific evaluation (for instance consistency check).
ANDRAS: I think, here we have to mention that we also publish data, which had not been available so far in the ESGF. GL : Is there any dataset in this case? Euro-CORDEX comes from the ESGF, even the new simulations from PRINCIPLES that are published on the ESGF first. Med-CORDEX will be published on the ESGF in a second step after the 34b Lot 1. And for 34d data, non-ESGF data will be published on the ESGF and ESGF data have been just Qc-ed for CDS. So I don't see any dataset that exist on the CDS which is/will be not on the ESGF. ANDRAS: OK, maybe some text as proposed below would be sufficient.
We can mention the additional effort (of 34d) to find the additional data for non-European domains. Maybe the link to the IPCC Atlas should be also mentioned. GL: I agree.
In addition, CORDEX data for CDS includes Persistent IDentifiers (PID) in their metadata which allows CDS users to report any error during the scientific analysis. The error will be at least documented on the ESGF Errata Service (http://errata.es-doc.org)
ANDRAS: would you check this link to the ERRATA, please, it does not work for me! GL: Bug with the web-service, solved now.
, but also planned to be documented in the CDS. The CDS aims to publish only the latest versions of the datasets.

The metadata provided in NetCDF files adhere to the Climate and Forecast (CF) conventions. The rules within the CF-conventions ensure consistency across data files, for example ensuring that the naming of variables is consistent and that the use of variable units is consistent.
File naming conventions ANDRAS: please check, if this convention is also held for the non

-European domains. I also think that there might be some amendment needed, because of the domain name and the resolution.
When you download a CORDEX file from the CDS it will have a naming convention that is as follows:
