Introduction: Regional And Planet-Encircling
Dust Storms Occur Episodically On Mars, Influencing
The Thermal Structure And Dynamics Of The Atmosphere. While Suspended Dust Particles Are Nearly Always Present In The Atmosphere Of Mars At Some
Background Level, Conditions May Arise That Promote
Vigorous Dust Lifting To Occur And Existing Local Or
Small-Scale Dust Storms To Grow Or Coalesce, Obscuring Vast Regions Of The Planet In A Thick Dust For Periods Ranging From A Few Days To Many Weeks [1].
When Dust Storms Occur, They Often Alter Atmospheric
Circulation [2, 3, 4, 5, 6, 7, 8], Change Surface Albedo
Patterns [9, 10, 11] And Modify Subsequent Transport
And Deposition Of Water And Co2 At The Poles [12, 13,
14]. Dust Storms, Regardless Of Their Scale, Are A Key
Aspect Of The Martian Dust Cycle. While A Community
Effort Is Being Put Forth To Characterize The Conditions
Necessary For The Onset, Growth, And Decay Of Dust
Storms, Little Is Still Known About Their Diurnal Variability.
