Introduction
Mars Is The Only Place Where It Has Been Observed That
The Main Atmospheric Constituent, Carbon Dioxide, Condenses As Clouds. Modeling These Clouds Remains A Challenge In The Community, Especially For Mesospheric Co2
Clouds As The Conditions In This Layer Of The Atmosphere
Is Difficult To Constrain With Observations And Our Knowledge Of The Cloud Formation Processes In These Conditions
Remains Limited.
The Recent Study On Co2 Cloud Modeling Shows The
Need For Water Ice Clouds As Cloud Condensation Nuclei (Ccn) In The Formation Of Co2 Mesospheric Clouds
