Abstract:
Even though the role of water ice clouds in the Martian atmosphere was
not well understood until the 2000s, they are now considered to play an
important role in the Martian climate and weather. Not only their
presence impacts the atmospheric structure and temperature by their
interaction with the incoming Solar radiation, but they are also a major
actor in the inter-hemispheric exchange of water across the planet, and
their formation affects the ability of water (or hydrogen) to be
further mobilized and to escape the planet. However, more observational
data are currently needed to better characterize the properties of water
ice clouds in order to better understand and model the evolution of the
Martian atmosphere. Thus, we present here the result of a two Martian
years monitoring of the properties of the Martian water ice clouds using
the data from the Atmospheric Chemistry Suite (ACS) instrument onboard
the ExoMars Trace Gas Orbiter (TGO) spacecraft, and comparisons with
predictions from the Mars Planetary Climate Model (PCM).
