Revisiting the Solar Wind Deceleration Upstream of the Martian Bow Shock Based on MAVEN Observations

The Astrophysical Journal
The solar wind deceleration upstream of the Martian bow shock is examined using particle and magnetic field measurements obtained by the Mars Atmosphere and Volatile EvolutioN (MAVEN).

Martian atmospheric O₃ retrieval development for the NOMAD-UVIS spectrometer [PDF]

, 2017
The composition of atmospheric trace gases and aerosols is a highly variable and poorly constrained component of the martian atmosphere, and by affecting martian climate and UV surface dose, represents a key parameter in the assessment of suitability for

The trapped heavy noble gases in recently found Martian meteorites [PDF]

, 2002
The composition of the trapped Ar, Kr, and Xe in the Martian meteorites Los Angeles, Say Al Uhaymir 005/008, and 094 is discussed and found to be consistent with a mixture of Martian mantle and atmosphere noble gases and terrestrial ...

Hypotheses for near-surface exchange of methane on Mars [PDF]

, 2016
The Curiosity rover recently detected a background of 0.7 ppb and spikes of 7 ppb of methane on Mars. This in situ measurement reorients our understanding of the Martian environment and its potential for life, as the current theories do not entail any ...

Breeding vectors and predictability in the Oxford Mars GCM [PDF]

, 2003
A breeding vectors approach is used to study the intrinsic predictability of the Martian atmosphere using the Oxford Mars General Circulation Model (MGCM).

A Thermal Plume Model for the Martian Convective Boundary Layer [PDF]

, 2013
The Martian Planetary Boundary Layer [PBL] is a crucial component of the Martian climate system. Global Climate Models [GCMs] and Mesoscale Models [MMs] lack the resolution to predict PBL mixing which is therefore parameterized.

The circulatory impact of dust from dust profile assimilation [PDF]

, 2018
We present results from a reanalysis of temperatures, dust columns and dust vertical profiles focussing on the assimilation, distribution and transport of dust in the martian atmosphere.

A new model describing Forbush Decreases at Mars: combining the heliospheric modulation and the atmospheric influence

Earth and Planetary Physics, 2020
Forbush decreases are depressions in the galactic cosmic rays (GCRs) that are caused primarily by modulations of interplanetary coronal mass ejections (ICMEs) but also occasionally by stream/corotating interaction regions (SIRs/CIRs).

The ISSI international study team on the martian PBL – status report and plan [PDF]

, 2008
Dynamical processes in the Martian boundary layer provide the means of communication between surface ice deposits and the free atmosphere, and the means of lifting dust from the surface.

Age of martian air: Time scales for martian atmospheric transport [PDF]

Icarus, 2019
Abstract The mean time since air in the Martian atmosphere was in the low-latitude boundary layer is examined using simulations of an idealized “mean age” tracer with the MarsWRF general circulation model. The spatial distribution and seasonality of the mean age in low- and mid-latitudes broadly follow contours of the mean meridional circulation ...
