[CF-metadata] Default datum for latitude and longitude?

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.

Cheers, Jon

WGS84?

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.

Cheers,

Mike.
