Dear Martin,
Thanks for your detailed explanation. I'd like to add a bit more information.
These variables are not joint distributions, they are 1D distributions for
different ranges of Z. The question is, does "histogram_of_X[_over_Z]" mean
that the Z coordinate has to be completely collapsed?
Dear Jonathan,
I'm sorry I didn't respond on the point about it being the first bin: I had not
intended the special value to be restricted to the first bin, so I guess there
is something ambiguous in my intial formulation which is giving this
impression. I agree that we should formulate any ext
Dear Martin
Ah, OK, thanks. I must have misunderstood.
Best wishes
Jonathan

Dear Jim
In Appendix A it does not say that the flag attributes are allowed for
coordinate variables - it has just "D" in the "Use" column. This is not an
argument why they shouldn't be if there is a need, but they weren't introduced
with that in mind. The use which you suggested for Martin's case
Dear Alejandro,
The two CMIP variables which I'm talking about are cfadDbze94 currently defined
as "CFAD (Cloud Frequency Altitude Diagrams) are joint height - radar
reflectivity (or lidar scattering ratio) distributions." and cfadLidarsr532,
which has the same definition. If they are not joint
Dear Martin,
You are right, those definitions are not correct.
