Hi Mike, Yes, that's what I've been doing so far, but I seem to remember someone telling me that models tend to be formulated on a spherical earth. But maybe if the precise geolocation of the model grid points is important (e.g. for small-scale models) the datum will always be specified, or a different projection used.

If you're picking one at random, I'd go for WGS84 - that's a pretty safe bet for a lot of remote sensed and GPS related data.
