[MITgcm-support] exf_interp

[Dimitris Menemenlis]

Georges, for ex_interp, you need to provide input forcing fields on a regular latitude/longitude grid that, at a minimum, spans the complete domain of integration.  That is, exf_interp cannot do extrapolation.  The latitude increments of the input fields are allowed to vary with latitude but the longitude increments are defined by a single number and therefore they need to be constant.  Dimitris
