Of Martian atmospheres, oceans, and fossils
Icarus, 1990 Abstract Based on the absence of extensive cratering on the northern Martian plains, it is suggested that these plains were the sites of ancient oceans, 2 to 3.5 Gyr ago, with a calculatable water depth of (≥) 0.7 km. Also it appears possible to interpret the crater density counts for Chryse and the highlands as implying that Mars had a fairly dense ...

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

Global distribution and climate sensitivity of the tropical montane forest nitrogen cycle
Nature 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.

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

Mie scattering and the Martian atmosphere [PDF]
Symposium - International Astronomical Union, 1971 It has been suggested that the discrepancy between radio occultation determinations of the Martian atmospheric surface pressure (3.8 to 7 mb) and those deduced from optical polarization measurements and a simple Rayleigh atmosphere model (about 10 mb) are the results of sub-micron sized aerosols in the Martian atmosphere.

MAVEN Observations of the Interloop Magnetic Reconnections at Mars
The 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.

Effects of Charged Martian Dust on Martian Atmosphere Remote Sensing
Remote Sensing, 2022 In this paper, the extinction property and optical depth of charged Martian dust at infrared band 3 THz–300 THz are studied using the Mie scattering theory.

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 ...
