Introduction Since The Beginning Of The 21st Century, Many Different Missions Have Provided Unvaluable Information About The Martian Atmosphere, Including Its Seasonal And Geographical Variability. So, Remote Sounding By Orbiters Such As Mars Global Surveyor And Mars Express Allowed For A Good Characterization Of The Dust, Water And Co2 Cycles In The Lower Atmosphere, As Well As Their Effects On The Temperature Structure (Smith, 2004; Montmessin Et Al., 2017). In Situ Measurements By Landers And Rovers Have Unveiled The Meteorological Structure Near The Surface Of The Planet (E.G. Savijarvi Et Al., 2019). The Thermosphere/Ionosphere Region, As Well As The Magnetosphere And Its Interaction With The Solar Wind, Have Been Explored By Mars Express And Specially The Maven Mission By A Combination Of Remote Sounding And Insitu Measurements (E.G. Bougher Et Al., 2017).
