As Stephen says the checker currently only validates versions 1.0 to
1.4 of the CF convention.
I was unaware that CF-1.5 had been officially released. I now see that
the CF-1.5 document was added a couple of weeks ago. Guess I must have
missed that announcement somehow. :-(
Once I have a list of all the differences, I will implement them in the
checker as soon as I can and announce the update on the cf-metadata
mailing list.
Cheers,
Ros.

It's good to receive some prompt feedback on the CF-checker download.
I have limited knowledge of how the tool really works so I'm going to
forward general questions to cf-metadata and Ros Hatcher. To answer
Luca's question below -- The checker expects the version option to be
between "1.0" and "1.4". I'm not sure what features would need adding
to support 1.5.
Also something that came up is that the "-u" option expects to be
given the location of the udunits2.xml file installed as part of
udunits-2 and not udunits.dat. It's usual location is
<UDUNITS-HOME>/share/udunits/udunits2.xml.
Cheers,
Stephen.

for download
Hi Stephen,
our SA installed the package, and I gave it a try, and it worked
really nicely... got a couple of warning on a few files that seemed
like the correct thing to have.
One question I have is that the package seems to think the latest
version of CF is 1.4, while it is indeed 1.5 - is that correct ?
-bash-3.2$ cfchecks -v 1.5
pcmdi.ipcc4.miroc3_2_hires.amip.run1.monthly.hus_A1_1979_2002.nc
WARNING: CF-1.5 is not a valid CF version.
Performing check against newest version CF-1.4
CHECKING NetCDF FILE:
pcmdi.ipcc4.miroc3_2_hires.amip.run1.monthly.hus_A1_1979_2002.nc
Anyway this is great - as soon as we have a wiki up for this
NASA-PCMDI effort, I will advertise the package to the other data
providers...
thanks again!
Luca

Hi all,
With the permission of Rosalyn Hatcher I have packaged the NetCDF-CF
compliance checker as a downloadable tarball. This is available on
the Python Package Index. This tool provides the best available
verification of NetCDF-CF compliance.
The cf-checker has 2 dependencies: cdms and udunits-2. If you are
managing an ESGF datanode you already have CDAT in /usr/local/cdat.
Alternatively you can use cdat_lite. Udunits2 will need installing
separately and the udunits dynamic library must be in your ld library
path (e.g. set LD_LIBRARY_PATH).
[cfchecker] http://pypi.python.org/pypi/cfchecker
[CDAT-lite] http://pypi.python.org/pypi/cdat-lite
[UDUNITS-2] http://www.unidata.ucar.edu/software/udunits
Once you have these dependencies either download the tarball, unpack
and run "python setup.py install" or use the easy_install tool to
download and install automatically with "easy_install cfchecker" (for
instance /usr/local/cdat/bin/easy_install cfchecker)
This makes the script "cfchecks" available. The help page follows.
Please feed back any installation issues to me and usage issues to Ros
and/or myself.
Cheers,
Stephen.
