Overview:
To Simulate The Non-Orographic Gravity Waves’
(Nonoro-Gw) Impacts On The Matian Upper Atmosphere, We Have Extended The Nonoro-Gw Scheme By
Gilli Et Al. (2020) Into The Thermosphere (I.E. Up To
The Exosphere 300 Km). By Revisiting The Scheme And
Adopting A New Set Of Parameters, The Scheme Is Now
Working When Extended Into The Upper Atmosphere.
Secondly, The Thermal Structure Below 100 Km Simulated By The Gcm With The Nonoro-Gw Scheme
Parametrization Is Found To Be Highly Consistent With
Mcs Observations. As Well As, A Description Of Recent Improvements In The Lmd-Mgcm Dust/Water
Cycle Model, Which When Coupled To The Nonoro-Gw
Scheme Tends To Correct Some Known Biases In The
