[CF-metadata] What do models assume for the shape of the Earth?

Im finally getting back to investigating how to connect netCDF to GIS
systems.

Here's a question to anyone who knows how models typically work:

Normally I dont see information in the netCDF file on the assumed shape
of the Earth, eg ellipsoidal flattening or even spherical radius. Is
that because it doesnt matter that much? Or is there an assumed standard
that everyone just knows about?

Is there a different answer for global vs regional models? At what
scale does this start to matter?

thanks for any info
