✦ Synopsis

It is possible to construct numerical models of the ice segregation process. However, the model is a discrete approximation of a nonlinear continuous process and thus is subject to somewhat more pronounced effects of node geometry and calculation frequency than linear models. The model more closely simulates natural frozen soil structure when vapor phase transport is included in the model structure. An iteration frequency of 10 s appeared sufficient to yield realistic results with the exponentially spaced node geometry employed in these tests.

In order to assess the thermal stability of polar ice deposits, we present model calculated temperatures of flat surfaces and surfaces within bowl-shaped and flat-floored polar impact craters on Mercury and the Moon. Our model includes appropriate insolation cycles, realistic crater shapes, multiple
