Additionally, the uncertainty related to internal variability of the climate system is sampled by running several simulations with the same RCM-GCM combination. On the forms, these are indexed as separate ensemble members (the naming convention for ensemble members is available in the documentation). For each GCM, the same experiment was repeatedly done using slightly different conditions (like initial conditions or different physical parameterisations for instance) producing in that way an ensemble of experiments closely related. More details behind these sequential ensemble numbers will be available in the detailed documentation.
On a general level in the CDS form for the RCM simulations “v” enumerates runs and not model versions. Runs numbers different from “v1” means new simulations relative to the first “v1” one. It might not mean a new version:
ANDRAS: we have to check, if this level of information is needed in this overview or that is enough in the documentation. Maybe one sentence about these "runs" is sufficient here.
GL: Agree with Andras. This paragraph burdens the overview.

All known issues about the CORDEX data are documented through the ES-DOC Errata Service : https://errata.es-doc.org/.
The data are produced by the participating institutes of the EURO-CORDEX, Med-CORDEX projects and several national contributions to CORDEX. ANDRAS: this sentence might be extended in the view of the non-European data. GL: "several national contributions" is not enough ? I don't know if the non-European domains were part of similar consortiums as EURO-CORDEX or Med-CORDEX. I let Manuel and Grisha on this. Jose, would you check this, please?
