Introduction: The Focus Of This Work Is To
Advance Our Understanding Of The Impact Of Global
Dust Storms (Gds) On The State Of Dust Reservoirs
Because Of Their Propensity For Dust Lifting And
Redistribution [1-4]. Mapping The Global Distribution
Of Surface Dust, And Identifying Dust Reservoirs Has
Been Carried Out Previously Using Derived Albedo
[6,1], Visible Imagery [7,8,3,9], And Dust Cover Index
Derived From Infrared Spectra [10].
Outstanding Questions Pertain To Dust Fluxes And
Include Whether Replenishing Of Dust Reservoirs Is
Necessary For Gds Initiation (I.E., “Are Dust Source
Regions Exhausted During Gdss?”). General
Circulation Models (Gcm) Initialized With A Finite
