#104: Clarify the interpretation of scalar coordinate variables -----------------------------+---------------------------------------------- Reporter: jonathan | Owner: [email protected] Type: enhancement | Status: new Priority: medium | Milestone: Component: cf-conventions | Version: Resolution: | Keywords: -----------------------------+---------------------------------------------- Comment (by jonathan): Steve and Mark have requested a statement of the purpose of this ticket. This is how I would describe it: The current version of the CF standard does not state clearly that a scalar coordinate variable implies the notional existence of a size-one dimension which has not been included in the netCDF file as a dimension of the data variable. We believe this to have been the intention of the authors, and that is preferable because it is the most obvious and simplest interpretation of the CF standard, and we therefore propose these changes to make that intention clearer. It is possible that the writers of some existing CF-netCDF files might have had a different interpretation, but the changes we propose would not invalidate any existing file. The ambiguity relates only to the logical interpretation of the file. Resolving the ambiguity is therefore important to the CF data model, which is under discussion in other tickets. Note that the above statement is a motivation for the ticket. It's not intended as new text for the CF standard document. The proposed changes are as shown in [https://cf-pcmdi.llnl.gov/trac/ticket/104#comment:9 comment 9].
