Hi Dan,
if we were starting from a blank sheet, that would be a strong point. As it is,
we are rather constrained by the existing practices in the community. I hope
that we can find an agreement along the lines
that

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

Hi.
Another approach could be to use flag_values and flag_meanings on
the coordinate variable to indicate one or more special coord

Hi.
Another approach could be to use flag_values and flag_meanings on the

Hello,
The histogram records frequencies of a single characteristic of a

about whether or not a cloud exists should not be formally a part of the

Hello,
the CF standard name list has two "histogram_ " entries, and in the CMIP6
data request we may need to add a third, a histogram_of_cloud_top_height.
Besides the standard name, we also need, for this new variable, a method of
encoding the "missing data" bin in the histogram. That is,
