Dear Jonathan, Thanks for the response. My comments below.

However this quantity could also, more familiarly, be called the > acceleration_due_to_gravity i.e. g. Is it g you mean?

Like what is described here: http://www.gradiometry.com/gradiometry In some cases, the unit used is the eotvos, but we prefer s-2. Perhaps just gravity_gradient ? > > > Radius from Geocenter > > standard_name: radius_from_geocenter > > unit: m > > I would suggest calling this distance_from_geocentre.
