Dear Martin
I don't think that anyone has responded on the CF email list to your detailed
email at the end of Jan, have they?

That is a pity and I hope that there will be other responses. Thank you for
your
Dear all
Brian has a good point that sect 5.3 allows that there might be missing data
in aux coord variables. Appendix A - which is equally ancient in the story of
CF :-) - is not consistent with this, because it didn't allow _FillValue or
missing_value atts for coordinates until sect 9 was

hemispheric products ...
there are non-existent points, at which the data vars have missing values and
the aux coord vars have (syntactically) valid values.
note that placing (syntactically) valid values in
Dear Randy
Thanks for the clarification. I see no problem in having missing data where
there are non-missing aux coord vars. This is a usual situation.
Best wishes

The only thing that designates a variable as an auxiliary coordinate
variable is the presence of the variable name in a coordinates attribute on
another variable. There is nothing intrinsic to the variable that
designates it as a coordinate variable. (Not so for true coordinate
variables.) For
Dear Jim

Formally, that is right. By definition, a CF aux coord var is one which is
named by a coordinates attribute. The

I think we have a number of valid use cases for missing data in aux
coordinates, and i would vote to allow that.
sorry i didnt really answer jonathan's concern. I would suggest this
wording:
Auxiliary coordinates do not have to be monotonic or have
suggest the more general but applications using the auxiliary coordinates to
work with data may respond unpredictably when the auxiliary coordinates are
missing.
