Abstract
We Report The Detection And Characterisation Of Atmospheric Gravity Waves On The Atmosphere Of Mars Using
Images From The Omega Spectrometer Onboard Mars
Express Space Mission. These Waves Have Already Been
Detected By Mex (Määttänen Et Al., 2010; Spiga Et Al.,
2012), Although There Is Still An Important Dataset Of
Unexploited Atmospheric Observations (Gondet And Bibring, 2018) To Be Analysed. In This Study We Started
To Build The First Catalogue Of Atmospheric Gravity Waves
And Morphological Parameters Using Omega/Mex Data
By Adapting The Technique That Was Already Used Successfully For Venus (Silva Et Al., 2021). Each Image Was
Navigated And Processed For Optimal Detection Of Wave
Features And Accurate Characterisation Of Wave Properties And Parameters Such As Time, Spatial Coordinates,
Horizontal Wavelength, Packet Length, Packet Width And
