Abstract:
Emirates Exploration Imager (Exi) Onboard
Emirates Mars Mission (Emm) Is A Multiwavelength Double Lens Camera Suitable For Observing The Martian Lower Atmospheric Phenomena Such
As Dust Storms. The Visible Channel Is Capable Of Producing Full Martian Disk (~2-5 Km Per Pixel Resolution) Images, Which We Have Used In This Work To
Characterize The Dust Storms Of The Current Season.
Notably, The Dust Storm Research Is Directly Aligned
With The Emm Science Objective On The Lower Atmosphere And Also To The Objective Of Correlating The
Lower And Upper Atmosphere [2]. It Is Worth Mentioning Emm Orbit With An Inclination Of 25° Enables
Exi To Get A Local Time Coverage Throughout The Longitude Range Every 9-10 Days [1, 4]. This Unprecedented Observation Allows Analyzing The Dust Storm
Characteristics With A Sub-Diurnal Time Scale, Which
Has Not Been Well Explored. One Of Such High Temporal Resolution Observations From Exi Is Given Here
As An Example (Figure 1).
The High-Dust-Loading Season Typically Starts Near
Solar Longitude (Ls) 180°, Which Can Be Marked From
Significantly High Background Opacity [3]. However,
