Modeling of HDO in the Martian atmosphere
, 2020 <p>Mars is known to have had a significant liquid water reservoir on the surface and the D/H ratio is an important tool to estimate the abundance of the early water reservoir on Mars and its evolution with time. The D/H ratio is a measure of the ratio of the current exchangeable water reservoir to the initial exchangeable water ...

Evaluation of the Atmospheric Chemical Entropy Production of Mars
Entropy, 2015 Thermodynamic disequilibrium is a necessary situation in a system in which complex emergent structures are created and maintained. It is known that most of the chemical disequilibrium, a particular type of thermodynamic disequilibrium, in Earth’s ...

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

Martian zeolites as a source of atmospheric methane [PDF]
Icarus, 2016 The origin of the martian methane is still poorly understood. A plausible explanation is that methane could have been produced either by hydrothermal alteration of basaltic crust or by serpentinization of ultramafic rocks producing hydrogen and reducing crustal carbon into methane.

Photochemistry of Methane and Ethane in the Martian Atmosphere [PDF]
Journal of Geophysical Research: Planets, 2020 AbstractWe develop an existing 1‐D photochemistry model to include a comprehensive description of organic chemistry on Mars that includes the oxidation products of methane (CH4) and ethane (C2H6),a longer‐chain hydrocarbon that can be used to differentiate between abiotic and biotic surface releases of CH4.

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.

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.
