Dear All,
I've made a couple of fixes to the CF checker:
1) If the variable is deemed unitless, then the checker will not flag an
error if either units=1 or the units attribute is omitted.
2) Fix bug where the checker was incorrectly complaining about a missing
units attribute on some dimensionless variables.
It's available for testing at:
http://puma.nerc.ac.uk/cgi-bin/cf-checker-2.0.3.pl
Let me know if you find any issues. If all's well I'll copy it to the
'live' location on Friday.
Regards,
Ros.

Dear Karl,
That is correct. If the variable is deemed unitless, then the checker
will not flag an error if either units=1 or the units attribute is
omitted.
If the units attribute is missing, it will, however, produce an
information message suggesting that the units attribute is added for
completeness.
Eg.
------------------
Checking variable: CHL_count
------------------
INFO (3.1): No units attribute set. Please consider adding a units attribute
for completeness.
I introduced the INFO category of message a while ago, for instances
where the checker couldn't be sure of an error (E.g. where an
attribute is being used in a non-standard way), to prompt the user to
double check that what they've put is actually what they meant.
I'll hopefully have a fixed version of the checker available tomorrow
for testing.
Regards,
Ros.

Dear Rosalyn,
I assume the checker will also not complain if the units attribute is
simply omitted when the variable is unitless (i.e., either units="1"
or the attribute is omitted result in the same behavior by the checker).
best regards,
Karl

Dear Rosalyn,
thanks so much for your reply and your works that is so important for
me. Infact "my" data are produced within MYOCEAN (european) project
and thay are going to test them! so it is important they do not failed
the CF checker test.
Best regards.
cristina
p.s.
Sorry if sometime I miss some e-mails and I didin't answer to them.
This is a very caotic working time....and I'm receiving so many e-mails.
Thanks to all the cf-metadata group to their help!
Citando Rosalyn Hatcher<r.s.hatc...@reading.ac.uk>:
I agree units should be set to "1" and I am currently in the process of
fixing the error in the CF Checker.
Regards,
Ros.

Cristina,
I recommend the unit "1" for that use.
If the CF checker doesn't like that unit, then it should be fixed,
IMO, because that unit is supported by both the US NIST and the BIPM.

Dear Roy,
Our variable "chlorophyll count" as is understandable by CF is the
number of individual measurements used to determine a chlorophyll value.
I do need to know what to put at "units" attribute for that variable.
I undestood by the CF convention 1.4 (appendix C) that I have to put
"units="1" as the chlorophyll count is a dimensionless variable...but
the CF checker found it as an error.
I try not to put the Unit attribute ...but again i get an error by che
cf chcker.......so.....
my question is: what unit shoudl I set for my chlorophyll count variable?
thanks for your help.
