Steve,
Where did you get the names for the variables?
Have you tried to check out the list of variables using ncdump -h ?
(sometime different tools report differen variable names - nco, cdo,
wct, etc.)
It is also very helpful to ask nco-related questions at Sourceforge
http://sourceforge.net/p/nco/discussion/
where Charlie provides support for NCO. He may resolve your issue much faster
Next time also provide a link to your sample file so others could also try
Hope this helps
