Currently, there is no easy way to tell which version of CMIP model data was used to run a recipe. The only way to find this out is to go and have a look at the provenance. If the CMIP input data is not stored in a directory with the version in it, that even requires looking up the tracking ID in the provenance and going and finding out the version of the model data that had that tracking ID. It would be much easier to re-run the recipe with the same data, if the ESMValCore would figure out the data version and write that out to the recipe that is copied to the output directory.
