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.
