THanks -- looking at that issue, it resulted in this in teh current standard:
""" 2.6.3. External Variables The global external_variables attribute is a blank-separated list of the names of variables which are named by attributes in the file but which are not present in the file. These variables are to be found in other files (called "external files") but CF does not provide conventions for identifying the files concerned. The only attribute for which CF standardises the use of external variables is cell_measures. """ Which is clearly similar / related, but doesn't help with the issue at hand - particularly as it is restricted to cell_measures. IN a sense, this is a broader problem -- we're not talking about refereing to particular variable per-se, but to an entire grid definition -- a concept that may not yet be included in CF, but will if/when UGRID is included. So maybe we should talk about this in: #153 ? -- Reply to this email directly or view it on GitHub: https://urldefense.us/v3/__https://github.com/cf-convention/cf-conventions/issues/357*issuecomment-1064562111__;Iw!!G2kpM7uM-TzIFchu!hpg6AFPfjPHmRYGRlZmduvUBTa7W271V5fVWeThCuwRVm6EaPM4tqYFAqNG0XLELmIhom1xr2cE$ You are receiving this because you are subscribed to this thread.
