Hi All,
I am not wild about using 'type'. I had to read the terms several times before I figured out what was being meant, because I could read it different grammatical ways.
A second problem is that it seems a particular definition will be linked to these terms (or did I miss something?), yet someone might reasonably want to use a different definition for high/middle/low clouds in the future.
Although I generally don't like including the origin of the data in the std_name, I think this may be an exception. I would suggest using either
ISCCP_high_cloud_area_fraction
ISCCP_middle_cloud_area_fraction
ISCCP_low_cloud_fraction
or
WMO_high_cloud_area_fraction
WMO_middle_cloud_area_fraction
WMO_low_cloud_fraction
I note that isccp_cloud_area_fraction is already an accepted std_name, so the suggestions above follow naturally.
This would also allow changes to the high/middle/low definitions in the future. This would be a problem if there is a proliferation of definitions, but I doubt this will be a problem.
Best wishes,
Philip

These look fine to me. As you said to John, I hope that "type" would trigger
people to look up the definition.
Best wishes and thanks
