Hi Mark,
i was unable to download the data from your ftp site, as the site didn't
seem to allow anonymous logins.

Regardless, I looked at the script you attached. You are correctly
attaching the 2D latitudes and longitudes to the array that houses your
ccsm data:
ccsm_at_lat2d = ccsm_if->TLAT ; has correct units
ccsm_at_lon2d = ccsm_if->TLONG

so no problem there. I'm guessing the error messages are being caused by
the fact that you are doing a calculation within your plot call, and
thus the metadata (including the attached lat2d/lon2d arrays) is/are
being destroyed:
change the above line to these 2 lines:
ccsm = ccsm/100. ; preserve metadata
and I bet that works.
Best regards,
