  We explain how GCM boundary condition choices such as ocean-lake
coverage-depth, rotation rate, atmospheric constituents and other factors
influence surface conditions in ROCKE-3D paleo-Venus simulations. Studies such
as these should also be considered when examining liquid water habitability in
similar exoplanet experiments. We also describe how one ingests 3D topographic
data from NASAs Venus Magellan Spacecraft radar observations into the ROCKE-3D
Planetary General Circulation Model.
