Hi Ajay,
Variables of character type are treated as dimensionless and the units
attribute is only mandatory for dimensional quantities.
So no it is not necessary for station_name to have units associated with it.

Ros.

Hi Rosalyn,
Thanks for the clarification. That leads me to another question
though, if the *station_name *is defined as an aux co-ordinate, is it
mandatory to have associated units with it?
Can the units for the *station_name *variable be left blank? Is the
*station_name *variable supposed to be monotonic?
Thanks,
Ajay

Hi Ajay,
In your netcdf file is *station_name* identified as an aux
coordinate variable by listing it in the *coordinates* attribute?
There is a mistake in the H2 example (and others) where
*station_name* should be identified as a aux coord var on the
*coordinates* attribute for humidity
I raised this and other defects in ticket 103 -
http://kitt.llnl.gov/trac/ticket/103
Hope this helps,
Regards,
Ros.

Hi Everyone,
Can anybody tell me the correct usage of the *cf_role* attribute?
From my gathering, the *cf_role* attribute should only be
attached to a coordinated variable (See appendix A
<http://cfconventions.org/1.6.html#attribute-appendix>).
But in the CF conventions document Example H.2., the *cf_role* is
being attached to the *station_name* variable.
When we do this, the CF compliance checker gives out an INFO
message stating that the *cf_role *attribute is being used in a
non-standard way.
Any inputs?
Thanks,
Ajay
