Background
Spacecraft Observations Provide A Global View Of
The Martian Atmosphere By Monitoring Its Behavior
Across The Planet. In Contrast, Landers And Rovers Provide Information On The Local Environment Around
Their Landing Sites.
The Mars Reconnaissance Orbiter (Mro) Has
Been Making Observations Since November 2006. A
Key Objective Of The Compact Reconnaissance Imaging Spectrometer For Mars (Crism) On Mro
(Murchie Et Al., 2007) Is The “Atmospheric Monitoring
To Characterize The Spatial And Temporal Properties Of
The Atmosphere For The Studies Of Climate, Weather And
Photochemistry”. We Report Atmospheric Water Vapor
Column Abundances At A Spatial Resolution Of ~ 1 Km
