For a spherical body of uniform density the value of g below the surface is
proportional to the radial distance of the location from the centre of the
sphere. For a spherically symmetric body only the mass contained within the
sphere below the point has any effect on the measured value of g.
The record for optical clocks is detecting the effect on frequency of a change
in elevation of 1cm or so.

Does that work when going down below the surface as well as when up above it?
(My last physics class was a long time ago. I remember doing the integrals
for computing the gravity inside a sphere, but don't remember the answer. I
wouldn't be surprised if a factor of 2 or pi was involved below the surface..)
