Will the new variable have the same data type and dimensions as the
original? Then just rename it (NCDF_VARRENAME) and then overwrite the
data (NCDF_VARPUT).

Otherwise you have to make a new file, copy over all the stuff you want
to keep, add the new stuff. The netCDF operators (NCO) are good for this
sort of thing:
