I think that is OK. In case it is not clear what "referencing variables" means it could be "all the data variables which refer to it". However, now I look again at ticket 85, which has been agreed already, and Rich drew our attention to it, I wonder whether we can't just go with that. "Missing data is allowed in data variables and auxiliary coordinate variables. Generic applications should treat the data as missing where any auxiliary coordinate variables have missing values; special-purpose applications might be able to make use of the data. Missing data is not allowed in coordinate variables." I guess we must have been through a similar discussion before. The above is more permissive than the words you suggest. It says it's allowed to have missing data in aux coord vars, but if you do that at any points where the data variable is non-missing, the data values there should be ignored i.e. treated as if they were missing. Is that all right? Best wishes Jonathan _______________________________________________ CF-metadata mailing list [email protected] http://mailman.cgd.ucar.edu/mailman/listinfo/cf-metadata
