Introduction:
Supercam On-Board The Mars2020-Perseverance
Rover Is A Suite Of Remote Sensing Instruments [1,2]
That Includes Passive Visible And Near-Infrared
(Visir) Spectroscopy Covering The Following Channels: 385–465 Nm, 536–853 Nm, And 1300–2600 Nm.
At These Wavelengths, The Scattering Of Light By Aerosols Is Strongly Sensitive To The Particle Size. By Observing The Martian Sky Light Scattered By Aerosols
(Dust And Water Ice Clouds), At Two Different Elevation
Angles With The Visir Technique, And By Comparing
The Measurement With The Results Of A Multiple Scattering Radiative Transfer Model, We Are Able To Retrieve And Monitor Aerosols Properties Such As The
Particle Sizes And Phase Functions. This “Passive Sky”
Technique Has Been Demonstrated In The Visible Range
With Chemcam On The Mars Science Laboratory
(Msl) Rover [3]. With Supercam, The Atmosphere Is
