Gravity waves and high‐altitude CO2 ice cloud formation in the Martian atmosphere [PDF]
We present the first general circulation model simulations that quantify and reproduce patches of extremely cold air required for CO2 condensation and cloud formation in the Martian mesosphere.

Martian Proton Aurora Brightening Reveals Atmospheric Ion Loss Intensifying
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 ...

Improved general circulation models of the Martian atmosphere from the surface to above 80 km
We describe a set of two “new generation” general circulation models of the Martian atmosphere derived from the models we originally developed in the early 1990s.

Thermospheric density responses to Martian dust storm in autumn based on MAVEN data
The unique seasonal surface dust storms on Mars have a significant impact on the Martian atmosphere. However, due to the lack of observations, semi-empirical models are difficult to simulate the density changes in the thermosphere with the existence of ...

Earth – Mars Similarity Criteria for Martian Vehicles [PDF]
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.

Cloud trains associated with Martian Mountain Lee Waves on the eastern side of the Phlegra Montes
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

Distribution of Dune Landform on Mars
Dune landforms are widely distributed on Mars and contain abundant information about the Martian atmosphere and sedimentary environment. At present, the understanding of Martian dunes and their environmental significance still needs to be further ...

Evolution of the Martian Atmosphere [PDF]
Carbon dioxide, nitrogen, and the nonradiogenic and radiogenic noble gases are tracked from primordial inventories to their present states in a revised model of atmospheric evolution on Mars. Elemental and isotopic abundances evolve by hydrodynamic escape, impact erosion, outgassing, sputtering, photochemical escape of nitrogen, and carbonate formation

Nucleation studies in the Martian atmosphere [PDF]
We developed models for unary nucleation of water and carbon dioxide in the Martian atmosphere. Both homogeneous and heterogeneous nucleation on dust particles were studied. Our models are based on classical theory. We compare results of different adsorption approaches.
