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

Nat 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.

Meteoric Metal Chemistry in the Martian Atmosphere. [PDF]

J Geophys Res Planets, 2018
Recent 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 ...

Clouds in the Martian Atmosphere

Oxford 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

Laser Ablation Sampling With Low-Power Plasma: A LA-MIP-MS Instrument for Spaceflight. [PDF]

Rapid Commun Mass Spectrom
ABSTRACT Rationale Inductively coupled plasma (ICP) is a commonly used ion source for mass spectrometry‐based chemical analysis of a wide range of materials. Traditional ICP ion sources use high power (> 1000 W) and significant gas flow (> 10 L/min), rendering them unsuitable for spaceflight, as they are too resource‐intensive for planetary spacecraft.

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

The 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 CO2 is known to induce strong isotopic fractionation of the carbon between CO2 and ...

Martian Dust Storms and Gravity Waves: Disentangling Water Transport to the Upper Atmosphere [PDF]

Journal of Geophysical Research: Planets, 2022
Simulations with the Max Planck Institute Martian general circulation model for Martian years 28 and 34 reveal details of the water “pump” mechanism and the role of gravity wave (GW) forcing.
