Alternate oscillations of Martian hydrogen and oxygen upper atmospheres during a major dust storm

open access: yesNature Communications, 2022
Dust storms on Mars drive water escape to space. Here, the authors show the impact Martian dust storms have on the abundance of atmospheric hydrogen and oxygen, and how this helps to overall oxidize the Martian atmosphere.

Simulation of Transient Topside Layer in the Martian Ionosphere

open access: yesRemote Sensing, 2023
Many Mars missions, e.g., Mariner, Viking, Mars Global Surveyor (MGS), Mars Express (MEX), and Mars Atmosphere and Volatile Evolution (MAVEN), have been launched to study the Martian atmosphere.

Diurnal Variations of Water Ice in the Martian Atmosphere Observed by Mars Climate Sounder

open access: yesRemote Sensing, 2022
Simulation studies have proposed a significant thermal effect of water ice clouds on the Martian atmosphere and climate. However, previous studies focused more on seasonal variations but less on short-term changes.

MAVEN Observations of the Interloop Magnetic Reconnections at Mars

open access: yesThe Astrophysical Journal, 2023
Magnetic reconnection between neighboring magnetic field loops, the so-called interloop reconnection, is a common process to drive flares in the solar atmosphere.

Evaluation of the Atmospheric Chemical Entropy Production of Mars

open access: yesEntropy, 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 ...

Martian Bow Shock and Magnetic Pile-Up Barrier Formation Due to the Exosphere Ion Mass-Loading [PDF]

open access: yesJournal of Astronomy and Space Sciences, 2011
Bow shock, formed by the interaction between the solar wind and a planet, is generated in different patterns depending on the conditions of the planet.

Tianwen-1 and MAVEN Observations of the Response of Mars to an Interplanetary Coronal Mass Ejection

open access: yesThe 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
