Hi Mark,
One example I know of:
area_type is a string type variable with standard values taken from:
http://cfconventions.org/Data/cf-standard-names/27/src/area-type-table.xml
This was used in CMIP5. The units in the standard name table are given
as "1".
best regards,
Karl

Hello CF
I understand that netCDF coordinate variables have to be strictly
monotonic, and no-one wants to define what this means for the general
case of strings; that is fine.
But I believe that I can create a CF auxiliary coordinate with string
values without any concern.
I am interested in whether there are cases in the standard names table
which explicitly state that a certain standard name should have string
values?
How might this be stated?
Do we have a canonical unit of 'no_unit' available?
thank you
mark
