Introduction Aerosols Are An Important Aspect Of The Martian Climate But Their Diurnal Variability Is Largely Unknown. Dust Is Ubiquitous In The Lower Martian Atmosphere, Absorbing And Scattering Incident Solar Radiation Which Warms Or Cools The Troposphere Depending On Local Conditions. Therefore, The Thermal State Of The Atmosphere Is Quite Sensitive To The Abundance And Distribution Of Airborne Dust (Kahre, Murphy, Newman, Wilson, Cantor, Lemmon And Wolff, 2017). Water-Ice Clouds Also Play A Role In The Climate, Though Often To A Lesser Extent Than Dust. These Clouds Absorb In The Infrared And Consequently They Influence The Global Temperature Structure And Water Vapor Transport (Clancy, Montmessin, Benson, Daerden, Colaprete And Wolff, 2017). Unfortunately, Many Sunsynchronous Spacecraft Did Not Take Observations That
