Abundance and Isotopic Composition of Gases in the Martian Atmosphere from the Curiosity Rover
Agreement between the isotopic ratios measured by SAM with those of martian meteorites, measured in laboratories on Earth, confirms the origin of these meteorites and implies that the current atmospheric reservoirs of CO2 and H2O were largely established after the period of early atmospheric loss some 4 billion years ago.
Mars methane detection and variability at Gale crater
Curiosity confirms the presence and variability of atmospheric methane, implying episodic production from an unknown source, and reports of plumes or patches of methane in the martian atmosphere that vary over monthly time scales have defied explanation.
Water Isotope Ratios D/H, 18O/16O, 17O/16O in and out of Clouds Map Dehydration Pathways
Water isotope ratios have been measured by laser absorption spectroscopy in and out of cirrus clouds formed in situ and convectively generated in anvils over subtropical regions, suggesting dehydration of upper tropospheric air occurs both by convective dehydration and by gradual dehydration mechanisms.
The Sample Analysis at Mars Investigation and Instrument Suite
The Sample Analysis at Mars (SAM) investigation of the Mars Science Laboratory (MSL) addresses the chemical and isotopic composition of the atmosphere and volatiles extracted from solid samples. The…

Good agreement is obtained, often within 5% to 10%, but the author points out certain issues to resolve and some larger systematic differences; some artifacts in the first publicly released MLS (version 1.5) dataset are noted.
Volatile, Isotope, and Organic Analysis of Martian Fines with the Mars Curiosity Rover
Samples from the Rocknest aeolian deposit were heated to ~835°C under helium flow and evolved gases analyzed by Curiosity's Sample Analysis at Mars instrument suite, suggesting that oxygen is produced from thermal decomposition of an oxychloride compound.
Aura Microwave Limb Sounder upper tropospheric and lower stratospheric H2O and relative humidity with respect to ice validation
 The validation of version 2.2 (v2.2) H2O measurements from the Earth Observing System (EOS) Microwave Limb Sounder (Aura MLS) on the Aura satellite are presented. Results from comparisons made…
Transport out of the lower stratospheric Arctic vortex by Rossby wave breaking
The fine-scale structure in lower stratospheric tracer transport during the period of the two Arctic Airborne Stratospheric Expeditions (January and February 1989; December 1991 to March 1992) is…
Background levels of methane in Mars’ atmosphere show strong seasonal variations
In situ measurements at Gale crater made over a 5-year period by the Tunable Laser Spectrometer on the Curiosity rover show large seasonal variation in the background and occurrences of higher temporary spikes that are consistent with small localized sources of methane released from martian surface or subsurface reservoirs.
Isotope Ratios of H, C, and O in CO2 and H2O of the Martian Atmosphere
Comparison between measurements in the modern atmosphere and those of martian meteorites such as ALH 84001 implies that the martian reservoirs of CO2 and H2O were largely established ~4 billion years ago, but that atmospheric loss or surface interaction may be still ongoing.
