Hi Bob,
I think this is because the name of the variable "T" from the file, is 
the same as the keyword T in Ferret which refers to time steps on axes.  
In the Users Guide, see "naming, variables in NetCDF files" for a 
discussion of this. Try putting the variable name in quotes

 yes? fill 'T'[k=1,l=1]

or you could rename it in your script

 yes? let my_t = 'T'[d=1]

You'll need to use the same upper or lowercase form of T that's in the 
file. Use ncdump,

 > ncdump -h filename.nc

to look at the file header and check which it is.
