Comparison of the results of water vapor modeling in the Martian atmosphere by the MAOAM model with data from the ACS instrument of the ExoMars mission for 34, 35 and 36 Martian years

The MAOAM (Martian Atmosphere: Observation and Modeling) model, also known as MPI-MGCM (Max Planck Institute Martian general circulation model) is a general circulation model of the Mars atmosphere with a spectral dynamical core. The model is quite successful in predicting the temperature regime on Mars and shows concordance with observational data. The hydrodynamic block of the model includes the transport scheme, water vapor and ice microphysics, heterogeneous nucleation, sedimentation, photodissociation, and surface water exchange, and reproduces the main features of the Mars hydrological cycle, such as the Aphelion cloud belt and water vapor transport from the northern hemisphere to the southern hemisphere. 

Modeling of the water cycle on Mars is performed for the 34th, 35th, and 36th Martian years. Seasonal-altitude and latitudinal-altitude distributions of atmospheric water vapor content, and temperature distributions will be presented. Comparisons of modeling results with averaged profiles obtained by the ACS (Atmospheric Chemistry Suite) spectrometer from the ExoMars Trace Gas Orbiter (TGO) spacecraft will be presented.
