Introduction: The North Polar Region Of Mars Is
A Very Active Region, From Dust Storms On The Scale Of
5000 Km To Polar Cliff Avalanches On The Scale Of A
Few Meters. In The Northern Winter And Summer, During The Formation And The Sublimation Of The Seasonal
Frost Cap, This Region Is Responsible For A Significant
Change In The Atmospheric Pressure [1]. Due To This,
The Seasonal Variation Of This Region Strongly Affects
Variation On The Entire Planet. A Strong Understanding Of This Region Will Help Us Predict The Future Climate For Martian Exploration And Understand The
Climate In The Past. There Are Many Features And Processes That Are Poorly Classified. We Focused On The
Cold And Bright Anomalies (Caba), First Observed
By Thermal Observations [2,3].
The Caba Are Cold And Bright Regions That Appear In Visual And Thermal Data Annually During Early
Summer [2]. There Are So Named Because They Respond Differently From Their Surroundings That Appear
To Have Otherwise Similar Properties. Equally Anomalous, During Late Summer, The Caba Rapidly Undergo
A Reduction In Albedo, Over Just A Few Hours - Becoming The Darkest Locations On The Polar Cap [2,3]. We
Used Observations From Mars Color Imager
(Marci), Thermal Emission Imaging System
