Tianwen-1 and MAVEN Observations of the Response of Mars to an Interplanetary Coronal Mass Ejection
The Astrophysical Journal, 2023 Interplanetary coronal mass ejections (ICMEs) are solar transients that have significant effects on the upper atmosphere and ionosphere of Mars. The simultaneous spacecraft observations from Tianwen-1/MOMAG in solar wind and multiple instruments on board

Influence of gravity waves on the climatology of high-altitude Martian carbon dioxide ice clouds [PDF]
Annales Geophysicae, 2018 Carbon dioxide (CO2) ice clouds have been routinely observed in the middle atmosphere of Mars. However, there are still uncertainties concerning physical mechanisms that control their altitude, geographical, and seasonal distributions.

Martian Proton Aurora Brightening Reveals Atmospheric Ion Loss Intensifying
Geophysical Research Letters, 2023 The Martian proton aurora is a distinct aurora phenomenon resulting from the direct deposition of solar wind energy into Mars' dayside atmosphere. What solar wind parameters influence the aurora activity in the short term is yet unknown, as are the ...

Earth – Mars Similarity Criteria for Martian Vehicles [PDF]
INCAS Bulletin, 2010 In order to select the most efficient kind of a martian exploring vehicle, the similarity criteria are deduced from the equilibrium movement in the terrestrial and martian conditions.

Modelling the martian atmosphere [PDF]
Astronomy and Geophysics, 2003 Mars general circulation models, used to study the atmosphere of Mars, have developed almost in parallel with terrestrial weather and climate models. These models are now being confronted with a large amount of new spacecraft data, which is allowing the models to be validated more rigorously. This paper briefly reviews the current state of Mars models,

The dust storm and its interaction with atmospheric waves on Mars
地球与行星物理论评, 2021 Mars shares many similarities with Earth. The comparative study of the climate between the two planets is of great significance to understand the evolution of the Earth's atmosphere.

Argon in the Martian atmosphere
Geophysical Research Letters, 1974 Heretofore undetected argon may be a significant constituent of the Martian atmosphere with a partial pressure of 1.8 mbar. The addition of argon to the 5.5±0.8 mbar of CO2, deduced from ground‐based spectroscopy, is consistent with the values of total pressure deduced from the Mariner radio occulation measurements. The presence of argon in the Martian

Cloud trains associated with Martian Mountain Lee Waves on the eastern side of the Phlegra Montes
Earth, Planets and Space, 2023 Mountain lee waves have often been observed on the eastern side of the Phlegra Montes as wave trains visualized by water ice clouds in the Martian atmosphere. The seasonality and formation condition of these lee waves and associated cloud trains have not
