Introduction:
To Understand The Evolving Martian Water Cycle
And Variations In Transport Of Water Throughout The
Atmosphere On Several Timescales (Diurnal To Seasonal), A Global Perspective Of The Combined Vertical And
Horizontal Distribution Of Water Is Needed. The Global
4-D Vertical Water Vapour Distribution Is Investigated
Through A Reanalysis That Unifies Water, Temperature
And Dust Retrievals From Several Instruments On Multiple Spacecraft Throughout Mars Year (My) 34 With
A Global Circulation Model. The Global Dust Storm
And Southern Summer Regional Dust Storm Events
Pushed Water Vapour Higher In Altitude Across All
Latitudes, And Supersaturated Water Vapour Is Found
To Penetrate The Northern Winter Polar Vortex. This
Analysis Provides New Insights Into Water Loss From
