Hi Paul,
From the CF Checker point of view, it does a comparison to ensure that
the units specified in the netcdf file are dimensionally equivalent to
those specified for the standard_name (if specified) in the Standard
Name table. For the standard_name "depth" the canonical units defined
are metres. Hence the error message you received. Hopefully, someone
will be able to advise if there is a more appropriate standard_name
available, which better matches your needs.
Regards,
Rosalyn.

Hi there Folks..
Just wondering about the use of the vertical coordinate depth, and in particular
"pressure" with the units "decibar"..
Seems to me that the conformance checker (v2.0.2) available at
http://puma.nerc.ac.uk/cgi-bin/cf-checker.pl doesn't much like "pressure" complaining
that the units "decibar" is not consistent with those in the standard_name (v1.5/v17
table:
<file>
double depth(depth) ;
depth:units = "decibar" ;
depth:units_long = "decibar (pressure)" ;
depth:long_name = "depth" ;
depth:standard_name = "depth" ;
depth:axis = "Z" ;
depth:positive = "down" ;
depth:bounds = "depth_bnds" ;
<checker output>
Checking against CF version 1.5...
...
Using CF Checker Version 2.0.2
Using Standard Name Table Version 17 (2011-03-24T11:54:30Z)
Using Area Type Table Version 1 (5 December 2008)
...
------------------
Checking variable: depth
------------------
ERROR (3.1): Units are not consistent with those given in the standard_name
table.
I'd appreciate some feedback if I have things around the wrong way here..
Cheers,
P
