Introduction: The Evolving Distribution Of
Radiatively Active Dust And Water Ice Clouds Plays A
Major Role In Modulating The Seasonal And
Interannual Variation In The Thermal Forcing Of The
Martian Atmosphere. Thermal Tides Are The Globalscale Atmospheric Response To The Diurnally Varying
Thermal Forcing Due To Aerosol Heating Within The
Atmosphere And Radiative And Convective Heat Transfer From The Surface. The Tide Includes Westward
Propagating (Sun-Synchronous) Waves Driven In
Response To Solar Heating, As Well As Nonmigrating
Waves That Result From Zonal Variations In The
Thermotidal Forcing Caused By Variations In Topography And Surface Thermal Properties And In The Distribution Of Aerosols (Dust And Water Ice Clouds).
The Migrating Tides Are Of Particular Interest,
