If PHIS is changed, SGH should be changed (which requires making
some assumptions). And just to be clear we're talking about going in and
editing the input data set, say doing "ncdump oldinput.nc >oldinput.txt;
change ORO in oldinput.txt; ncgen -o newinput.nc newinput.txt;".
Make sure you check all the ccmi* initial fields and make sure
they're commensurate, otherwise you'll be putting in mountains where you
have no land.
