     9 The implementation of Radiatively Active Clouds (RACs) in the GCM, along with a full cloud microphysics scheme, allows for a satisfying agreement between simulated Global Water Cycle and TES observations regarding atmospheric water vapor and cloud opacity (figure 1). In this configuration, the Northern polar cap is set as an infinite ground ice reservoir avalaible for sublimation (figure 2). The global water cycle is sensitive to four main parameters listed in the table below.
