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

Modeling the variations of Dose Rate measured by RAD during the first MSL Martian year: 2012-2014 [PDF]

, 2015
The Radiation Assessment Detector (RAD), on board Mars Science Laboratory's (MSL) rover Curiosity, measures the {energy spectra} of both energetic charged and neutral particles along with the radiation dose rate at the surface of Mars.

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 ...

A review of volatiles in the Martian interior [PDF]

, 2016
Multiple observations from missions to Mars have revealed compelling evidence for a volatile-rich Martian crust. A leading theory contends that eruption of basaltic magmas was the ultimate mechanism of transfer of volatiles from the mantle toward the ...

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.

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 ...

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 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.

Kinetic model of carbonate dissolution in Martian meteorite ALH84001 [PDF]

, 2003
The magnetites and sulfides located in the rims of carbonate globules in the Martian meteorite ALH84001 have been claimed as evidence of past life on Mars.
