Introduction:
Since The Beginning Of The Mission, The Mars Science Laboratory (Msl, Curiosity) Has Observed The
Behavior Of Overhead Aerosols Through Movies Taken
By The Navigation Camera (Navcam). These Movies
Are Useful To Capture A Variety Of Parameters Such As
Optical Depth [1,2] And Aerosol Motion [3]. With An
Average Cadence Of 3-4 Sols, A Seasonal Record Of
Observed Wind Directions Can Be Created And Analyzed For Five Mars Years (Mys).
Wind Studies Have Been Completed At Gale Crater
Using The Rover Environmental Monitoring Station
(Rems) [4,5,6]. However, This Only Provides Near
Surface Winds And The Loss Of Boom 1 Restricts Rems
From Properly Measuring Wind Direction If The Incoming Winds Relative To The Rover Is Between 90 And 270
