The dust storm and its interaction with atmospheric waves on Mars

open access: yes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.

Nitrogen Fixation at Paleo‐Mars in an Icy Atmosphere

open access: yesGeophysical 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.

Quantification of Carbonates, Oxychlorines, and Chlorine Generated by Heterogeneous Electrochemistry Induced by Martian Dust Activity

open access: yesGeophysical Research Letters, 2023
Heterogeneous electrochemistry induced by Martian dust activity is an important type of atmosphere‐surface interaction that affects geochemical processes at the Martian surface and in the Martian atmosphere.

EMIRS Observations of the Aphelion‐Season Mars Atmosphere

open access: yesGeophysical Research Letters, 2022
Thermal infrared spectra taken by the Emirates Mars Infrared Spectrometer (EMIRS) on‐board the Emirates Mars Mission (EMM) spacecraft are well suited for the retrieval of surface temperatures, the atmospheric temperature profile from the surface to ∼40 ...

Patchy Proton Aurora at Mars: A Global View of Solar Wind Precipitation Across the Martian Dayside From EMM/EMUS

open access: yesGeophysical Research Letters, 2022
Proton aurora at Mars are thought to form indirectly, as a result of solar wind proton charge exchange with planetary coronal hydrogen upstream of the bow shock.

The impacts of coronal mass ejections on the space environments of Venus and Mars

open access: yes地球与行星物理论评
Coronal mass ejections (CME) are solar transients, and their impacts on the planets within the solar system have attracted considerable attention. As neighboring planets within the solar system, Venus and Mars are also directly and indirectly affected by

THz generation from laser-induced breakdown in pressurized molecular gases: on the way to terahertz remote sensing of the atmospheres of Mars and Venus

open access: yesNew Journal of Physics, 2020
The present paper studies the generation of terahertz (THz) radiation in CO _2 in comparison with atmospheric air at a wide range of pressures. We established experimentally and explained theoretically that for these gases there are optimal pressures at ...

Observation based climatology Martian atmospheric waves perturbation Datasets

open access: yesScientific Data, 2023
The Martian atmospheric waves perturbation Datasets (MAWPD) version 2.0 is the first observation-based climatology dataset of Martian atmospheric waves. It contains climatology-gridded temperature, gravity waves, and tides spanning the whole Martian year.

Sintering of ceramics for clay in situ resource utilization on Mars

open access: yesOpen Ceramics, 2020
The sintering of wet processed Mars global simulant green bodies is explored. Green bodies shaped using slip casting, throwing on a potter’s wheel and additive manufacturing, including material extrusion (robocasting) and layerwise slurry deposition (LSD)

An estimation of the mass dragged by the solar wind from Mars’s atmosphere in its geologic history [PDF]

open access: yesGeofísica Internacional, 2001
In the past Mars had a denser atmosphere, but it lacks a magnetic field to protect the ionosphere and exosphere from the solar wind. A model for describing the loss of atmosphere in geologic time is presented.
