Dear John > Im not sure if we ever converged on how to write ensemble files. No, we didn't. If I remember correctly, we couldn't agree on the relationship between attributes and coordinates, and that was a sticking-point. I thought that we ought to allow multivalued auxiliary coord variables for ensemble axes, corresponding to attributes that might be used to describe a single model. I would give these standard_names to identify them. Paco started the discussion, and in the end he made his own decisions for what to do for the ENSEMBLES project (because CF had not concluded), so he might comment on it.
> Particularly, how does software recognize the ensemble dimension? We didn't agree. But at the end of the discussion, Steve also suggested that it could be identified by an axis attribute, just as you have. I like that idea too. But it could also be given a standard name, like other coordinate variables e.g. ensemble_member_identifier. I suppose the values of this coord var might be either numeric or strings, though it your example it is integer. I haven't looked at the trac ticket to see if we discussed these points before. > Perhaps we should add :axis = "Ensemble" to the model coordinate variable? I'd suggest lower case, like most CF keywords. The other axis attributes are all single letters (X Y Z T) but I don't think it would be a problem to use a word.
