Meteoric Metal Chemistry in the Martian Atmosphere. [PDF]

open access: yesJ Geophys Res Planets, 2018
AbstractRecent measurements by the Imaging Ultraviolet Spectrograph (IUVS) instrument on NASA's Mars Atmosphere and Volatile EvolutioN mission show that a persistent layer of Mg+ ions occurs around 90 km in the Martian atmosphere but that neutral Mg atoms are not detectable.

Clouds in the Martian Atmosphere [PDF]

open access: greenOxford Research Encyclopedia of Planetary Science, 2018
Although resembling an extremely dry desert, planet Mars hosts clouds in its atmosphere. Every day somewhere on the planet a part of the tiny amount of water vapor held by the atmosphere can condense as ice crystals to form mainly cirrus-type clouds. The existence of water ice clouds has been known for a long time and they have been studied for decades,

Strong Depletion of 13C in CO Induced by Photolysis of CO2 in the Martian Atmosphere, Calculated by a Photochemical Model [PDF]

open access: yesThe Planetary Science Journal, 2023
The isotopic signature of atmospheric carbon offers a unique tracer for the history of the Martian atmosphere and the origin of organic matter on Mars. The photolysis of CO _2 is known to induce strong isotopic fractionation of the carbon between CO _2 ...

Dust tides and rapid meridional motions in the Martian atmosphere during major dust storms. [PDF]

open access: yesNat Commun, 2020
The atmosphere of Mars is strongly affected by the spatial and temporal variability of airborne dust. However, global dust variability within a sol (Martian day) is still poorly understood.

Bow shock oscillations of Mars under weakly disturbed solar wind conditions [PDF]

open access: yesNature Communications
Bow shock, where the solar wind first encounters the Martian environment, reflects the complex interplay between the solar wind and Martian upper atmosphere and crustal fields.

Impact sculpting of the early martian atmosphere. [PDF]

open access: yesSci Adv
Intense bombardment of solar system planets in the immediate aftermath of protoplanetary disk dissipation has played a key role in their atmospheric evolution. During this epoch, energetic collisions will have removed substantial masses of gas from rocky planet atmospheres.

The value of returning a sample of the Martian atmosphere. [PDF]

open access: yesProc Natl Acad Sci U S A
The elemental and isotopic abundances of major species in the Martian atmosphere have been determined, but analyses often lack sufficient precision, and those of minor and trace species are frequently not well known. Many important questions about the evolution and current state of Mars require the kind of knowledge that can be gained from analysis of ...

Discovery of a wind-driven diamagnetic current system in the Martian magnetosphere [PDF]

open access: yesScientific Reports
Magnetic fields around Mars shape the pathways of energy input into, and ion escape from, the Martian atmosphere, thereby potentially affecting the atmospheric evolution of Mars.
