In order to undertake credible studies of the Martian climate at other epochs, one requirement is a mechanistic understanding of the processes controlling the water cycle. This need arises from the increasing role of atmospheric water ice and vapour as radiatively active species as global atmospheric water abundances increase. Further, a key motivation for modeling past climates is the need to understand temporal variations in the amounts, state, and locations of water. We have investigated the processes controlling the water cycle with the Geophysical Fluid Dynamics Laboratory (GFDL) Mars General Circulation Model (GCM). These simulations suggest that primary parameters controlling current global atmospheric water abundance are the albedo and thermal inertia of the northern residual water ice cap, which in turn will be controlled by the macro- and microphysical properties of the ice. Additional information is contained in the original extended abstract.
