Introduction:
Understanding The Current Water Cycling In And
Out Of The Polar Regions Is Key To Unraveling The Climatic History Of Mars. Atmospheric Circulation Provides The Main Mechanism For The Transport Of
Around One-Third Of The Mass Of Water In And Out Of
The Polar Caps And In The Annual Exchange Between
The Northern Hemisphere To The Southern Hemisphere
And Back Through The Cross-Equatorial Hadley Circulation [1, 2]. Meanwhile Up To ~ 1010-1011 Kg Of Water Is Deposited Every Year At The Surface Near The
South Pole Due To The Permanent Cold Trap For Water
Vapor Maintained By The Presence Of A Residual Co2
Ice Layer Near The South Pole [3,4]. Placing Limits On
The Modern-Day Transport Of Water Into The Poles, And
The Water Deposition Rate In The South Polar Region
(Spr) Will Allow Us To Better Comprehend Its Important Role In The Mass Balance And The Modern-Day
Stability Of The Polar Ice Cap.
