Trace gas assimilation of Mars orbiter observations [PDF]

, 2012
Ozone, water vapour and argon are minor constituents in the Martian atmosphere, observations of which can be of use in constraining atmospheric dynamical and physical processes.

Unique, non‐Earthlike, meteoritic ion behavior in upper atmosphere of Mars

Geophysical Research Letters, 2017
Interplanetary dust particles have long been expected to produce permanent ionospheric metal ion layers at Mars, as on Earth, but the two environments are so different that uncertainty existed as to whether terrestrial‐established understanding would ...

Using Spatial Data Science in Energy-Related Modeling of Terraforming the Martian Atmosphere

Energies, 2022
This paper proposes a methodology for numerical modeling of terraforming Mars’ atmosphere using high-energy asteroid impact and greenhouse gas production processes. The developed simulation model uses a spatial data science approach to analyze the Global

The present and past climates of planet Mars

EPJ Web of Conferences, 2009
Mars is a small planet with a thin atmosphere of almost pure carbon dioxide. To first order, the Martian meteorology can be compared with what one would expect on a cold, dry desert-like Earth.

Properties and models of the Martian bow shock

地球与行星物理论评, 2021
Mars does not have a global magnetic field of the internal origin, thus, the solar wind plasma can interact directly with the upper atmosphere and the ionosphere and be shocked with the mass-loading and magnetic pileup processes.

Nitrogen Fixation at Paleo‐Mars in an Icy Atmosphere

Geophysical Research Letters
Recent findings of NO near Gale Crater on Mars have been explained by two pathways: formation of nitric acid (HNO3) in a warm climate or formation of peroxynitric acid (HO2NO2) in a cool climate.

Effects of the 2018 Martian Global Dust Storm on Boundary Positions in the Induced Magnetosphere

The Planetary Science Journal
Global dust storms at Mars have a significant impact on the atmosphere and ionosphere, but only recently has their impact on the magnetosphere been investigated.

Methane on Mars: Thermodynamic Equilibrium and Photochemical Calculations [PDF]

, 2010
The detection of methane (CH4) in the atmosphere of Mars by Mars Express and Earth-based spectroscopy is very surprising, very puzzling, and very intriguing. On Earth, about 90% of atmospheric ozone is produced by living systems.
