A set of 25 core variables from the CORDEX archive were identified for the CDS. These are the most used of the CORDEX data. These variables are provided from 5 CORDEX experiment types (evaluation, historical and 3 RCP scenarios) that are derived (downscaled) from the CMIP5 experiments. ANDRAS: I think, we have to indicate here, that for the non-European domain we provide lass variables and maybe in the table below indicate, which ones are only for the EURO-CORDEX or meMed-CORDEX domains.
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)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. 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.
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) but ANDRAS: would you check this link to the ERRATA, please, it does not work for me! but also planned to be documented in the CDS. The CDS do not aim to archive all dataset versions. Some version could be unpublished in the case of critical issues or outdated dataset. In general, the latest version of each dataset remains published on the CDSaims to publish only the latest versions of the datasets.
Domains
We are aiming at publishing various CORDEX domains for the entire World. The CDS-CORDEX subset at the moment consists of the Europe (EURO), Mediterranean (MED), North America (NAM) and Arctic (ARC) CORDEX domains More details are available for the EURO-CORDEX activities at https://www.euro-cordex.net/. More details of the entire list of CORDEX domains can be found at https://cordex.org/domains/.
Please note that the domains are not on regular grids. Projections may differ depending on the domain and the Regional Climate Model (RCM). The coordinates below are the maximum and minimum values of the domain window. As a summary, the available domains are:
