Hi Waylon,
There are multiple ways to do this with NCO, though none appear
to be quite as elegant as nc_eqn for this job. For example,
http://nco.sf.net/nco.html#ncatted
can do this by creating a missing_value attribute, changing it,
then deleting it:
ncatted -a missing_value,X,o,f,32 -a missing_value,X,o,f,45 \
-a missing_value,X,d,, F.nc G.nc
If needed, this command can be extended to backup and restore any
original missing_value attribute (e.g., temporarily change its name).
An ncap solution would torture the rounding functions in a manner
unbefitting to our society.
