Hi Karl,
Christina's problem is because her usage of standard name modifier is changing
the canonical units from those of the unmodified Standard Name. Only solutions
I can see are either to omit the Standard Name from this channel or set up a
new Standard Name for raw chorophyll as counts. The latter seems to me to be
not be as easy as it sounds. Any other opinions?
Cheers, Roy.

Hi Chritina,
For dimensionless variables, you can either omit the units attribute or set it
to "1". I don't understand why this error is raised. Did you assign a
"standard_name" to CHL_count? If so, what did you assign?
thanks,
Karl

Hello,
I have a problem. iN MY NETCDF FILE I define the CHL_count variable.
it is a dimensionless variable.
I used the "standard name modifier: COUNT" for the variable CHL.
for IT I define: units="1" as indicated in the Appendix C of the
"cf-conventions1_4.pdf".
but the cf checker gives me this error:
------------------
Checking variable: CHL_count
------------------
ERROR (3.1): Units are not consistent with those given in the
standard_name table.
WHAT SHOULD I PUT FOR THE ATTRIBUTE UNITS FOR THE CHL_COUNT VARIABLE?
IT IS DIMENSIONLESS!
THANKS IN ADVANCE
