Introduction
Gravity Waves Play An Important Role In The Dynamics
And Maintaining The Thermal Structure Of All Planetary
Atmospheres [YiğIt And Medvedev, 2019]. On Mars, They
Are Generated In The Lower Atmosphere And Propagate Upward To The Mesosphere And Thermosphere, Where They
Saturate And Deposit Their Energy And Momentum To The
Mean Flow. Here, We Present Recent Progress In The Observation Of Upper Atmospheric Effects Of Gravity Waves,
Focusing On Observations Provided By The Ngims Instrument Onboard Nasa’S Maven Spacecraft.

Thermospheric Gravity Waves During Dust Storms
Gravity Waves Continuosly Propagate From The Lower Atmosphere To The Thermosphere. Since Global Dust Storms
Significantly Change The Large-Scale Dynamical And Thermal Structure, Especially, Of The Lower Atmosphere, It
Is Expected That The Generation, Propagation, And Dissipation Of Gravity Waves Are Influenced By Dust Storms.
