Thanks to Wesley for this response and the replies offline.

To move to the practical implementation, is out there anyone who has
actually used GrADS and the PDEF entry for this type of purpose and
might even provide me with either further advice in or even sample
Fortran code for generating the needed binary file for the "PDEF
file" or "PDEF bilin" approach?

I have read the PDEF documentation, but to me it does not specify the
approach (for this application, anyway) in sufficient detail and I am
a bit in a hurry to do lots of trial and error; hence pointers,
advice or samples would be extremely helpful.
