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 ...

Wind measurements in Mars' middle atmosphere at equinox and solstice: IRAM Plateau de Bure interferometric CO observations [PDF]
Second workshop on Mars atmosphere modelling and observations,
held February 2 7 - March 3, 2006 Granada, Spain. Edited by F. Forget, M.A.
Lopez-Valverde, M.C. Desjean, J.P. Huot, F. Lefevre, S. Lebonnois, S.R.
Lewis, E. Millour, P.L. Read and R.J. Wilson. Publisher : LMD, IAA, AOPP,
CNES, ESA, 2006., p.134, Espagne (2006), 2007 Characterizing the Martian atmosphere is an essential objective to understand its meteorology and its climate. The lower atmosphere (< 40 km) and middle atmosphere (40-80 km) of Mars appear dynamically coupled at much higher levels than in the case of the Earth.

EMIRS Observations of the Aphelion‐Season Mars Atmosphere [PDF]
Geophysical 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 ...

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.

Probing Dust and Water in Martian Atmosphere with Far-Infrared Frequency Spacecraft Occultation
Remote Sensing, 2023 Airborne dust plays an active role in determining the thermal structure and chemical composition of the present-day atmosphere of Mars and possibly the planet’s climate evolution over time through radiative–convective and cloud microphysics processes ...
