[MITgcm-support] variable gravity for hydrostatic, r*, atmospheric model

Hello, I will make my yearly plea:
Could someone modify the model such that gravity varies as a function of
height, i.e. g(r)=GM/r^2, for the hydrostatic, r-star, atmospheric model
configuration? I use the MIT GCM to model Pluto, which has a solid
surface radius of 1180 km (give or take 50 km), and take the model up to
600 km altitude. The approximation that g = surface gravitational
constant at that height is a very bad approximation. Now I am taking
the model up to 2000 km altitude (note this is still below the exobase
and the continuum fluid approximation still applies), and this
approximation has become downright ridiculous.
Thanks,
Angela
