Non-migrating tides in the Martian thermosphere
… longitudinal structures associated with non-migrating tides in observations of the upper neutral atmosphere of Mars. MAVEN’s Imaging Ultraviolet Spectrometer (IUVS) observations of the upper atmosphere reveal variations in density with longitude at altitudes of 130 – 200 km, and can be …

Observations of Non-Migrating Tides in the Middle Thermosphere
Non-migrating tides are understood to be an important coupling mechanism through which lower atmospheric conditions influence the variability of the near-Earth space environment. Tidal variations have been exhaustively characterized in the mesosphere/lower thermosphere and the upper thermosphere, …

Vertically Propagating Tides in the Martian Atmosphere
Atmospheric tides significantly influence the dynamics of Mars' upper atmosphere. The impact of tides on the mean state of the present-day Martian atmosphere is especially large at high altitudes. Certain tides can propagate away from the region of generation in the lower atmosphere and reach the …

Modelling Mesopause OH* Emissions using a Global Circulation Model
… and suggest an underestimation of the effects of non-migrating tides. Migrating tides are shown to modulate the emission, in particular at the low latitudes although reduced effects are also observed in the mid- to high-latitude regions. Migrating tides have proven difficult in previous modelling …
