14. The 1D thermal model is based on that of Vasavada et al. (19) and includes vertical conduction and surface emission as well as temperature-dependent thermal conductivities and heat capacities. Our ice sublimation and vapor diffusion model is based on that of Fanale and Salvail (20) for comets, where we have adapted the thermal model to adjust thermophysical properties according to local ice content. Unless otherwise indicated, we assume a porosity of 50%, mean grain separation of 70 μm, and infrared emissivity of 0.95.
