Observations of Atmospheric Tides in the Middle and Upper Atmosphere of Mars From MAVEN and MRO. [PDF]
J Geophys Res Planets, 2022 Variability in the Martian upper atmosphere is strongly linked to the lower atmosphere and much of it can be attributed to vertical wave propagation. Atmospheric tides in particular are a well‐known phenomenon in the Martian atmosphere that play a key ...

The atmosphere of Mars as observed by InSight [PDF]
Nature Geoscience, 2020 The atmosphere of Mars is thin, although rich in dust aerosols, and covers a dry surface. As such, Mars provides an opportunity to expand our knowledge of atmospheres beyond that attainable from the atmosphere of the Earth. The InSight (Interior Exploration using Seismic Investigations, Geodesy and Heat Transport) lander is measuring Mars’s atmosphere ...

Constraints on the Size and Composition of the Ancient Martian Atmosphere from Coupled CO2–N2–Ar Isotopic Evolution Models [PDF]
The Planetary Science Journal, 2023 Present-day Mars is cold and dry, but mineralogical and morphological evidence shows that liquid water existed on the surface of ancient Mars. In order to explain this evidence and assess ancient Mars’s habitability, one must understand the size and ...

Microwave spectroscopy of the Mars atmosphere [PDF]
Applied Optics, 1995 A study of the use of millimeter-wavelength spectral transitions to investigate the atmosphere of Mars is presented. In the model experiments investigated it is assumed that a spectrometer in the frequency range from 100 to 260 GHz looks into a modest ...

Primordial argon isotope fractionation in the atmosphere of Mars measured by the SAM instrument on Curiosity and implications for atmospheric loss. [PDF]
Geophys Res Lett, 2013 The quadrupole mass spectrometer of the Sample Analysis at Mars (SAM) instrument on Curiosity rover has made the first high‐precision measurement of the nonradiogenic argon isotope ratio in the atmosphere of Mars. The resulting value of 36Ar/38Ar = 4.2 ±

MAVEN observations of solar wind hydrogen deposition in the atmosphere of Mars
Geophysical Research Letters, 2015 Mars Atmosphere and Volatile EvolutioN mission (MAVEN) observes a tenuous but ubiquitous flux of protons with the same energy as the solar wind in the Martian atmosphere. During high flux intervals, we observe a corresponding negative hydrogen population.

Fractional Diffusion Models for the Atmosphere of Mars [PDF]
Fractal and Fractional, 2017 The dust aerosols floating in the atmosphere of Mars cause an attenuation of the solar radiation traversing the atmosphere that cannot be modeled through the use of classical diffusion processes.

Atmospheric oxidation drove climate change on Noachian Mars [PDF]
Nature CommunicationsModern Mars is bipolar, cold, and oxidizing, while early Mars was characterized by icy highlands, episodic warmth and reducing atmosphere. The timing and association of the climate and redox transitions remain inadequately understood. Here we examine the
