Results from the Viking Orbiter Mars Atmospheric Water Detectors (MAWD) have long been the definitive data set for observations of the Martian water cycle (Farmer et al., 1977). The ongoing Mars Global Surveyor Thermal Emission Spectrometer (TES) observations are providing new insights into the current water cycle, with detailed ongitude-latitude dependence of water vapour (Figure 1) and water cloud (Figure 2) with time, as well as information on vertical distribution of water vapour and ice cloud (Smith, 2001). The described results are derived from an ongoing project to model the current water cycle using the Oxford version of the European Mars General Circulation Model (MGCM) (Forget et al., 1999), which was developed in colaboration with LMD, Paris.
