Introduction Climates On All Planets Are Heavily Influenced By Aerosols In Their Atmospheres. Their Nature, Size’S Distribution And Content Affect The Energy Budget, Hence The Atmospheric Dynamic Of The Planet. On Mars, We Know That Three Types Of Aerosol Exist. Dust, Water Ice And Carbon Dioxide Ice. Dust Mainly Affects The Thermal Structure Of The Martian Atmosphere Through Radiative Heating [1]. Water Ice Has A Broader Effect Since It Impacts The Thermal Structure, As For Dust, Through Modifying The Radiative Equilibrium [2] But Also The Martian Water Cycle [3]. Carbon Dioxide Ice Condensation Occurs Mainly Close To The Poles During Winter Or At High Altitudes [4]. Water And Carbon Dioxide Ice Also Influence Dust Content And Size Distribution Through Their Condensation Onto Smaller Dust Particles Acting As Condensation Nuclei [5].
