Modeling of the Martian Water Cycle with an Improved Representation of Water Ice Clouds

The Martian water cycle has been studied for a long time thanks to remote observations and the use of GCMs (Global Climate Model). Thanks to GCMs, the comprehension of the water cycle has been improved, revealing for instance the impor- tance of clouds in the global water transport [5] with implications for atmospheric dynamics, paleo- climates. From that perspective, the modeling of the Martian water cycle by the LMD (Laboratoire de Météorologie Dynamique) Mars GCM has been im- proved by implementing significant processes, such as radiatively active water ice clouds and a micro- physical scheme described in [4], including pro- cesses such as nucleation, growth of ice particles, sedimentation, coalescence and scavenging of dust nuclei
