TL;DR: 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.

The Modern Near-Surface Martian Climate: A Review of In-situ Meteorological Data from Viking to Curiosity
German Martinez,C. N. Newman,A. De Vicente-Retortillo,E. Fischer,Nilton O. Renno,Mark I. Richardson,Alberto G. Fairén,Alberto G. Fairén,Maria Genzer,Scott D. Guzewich,R. M. Haberle,Ari-Matti Harri,Osku Kemppinen,Mark T. Lemmon,M. D. Smith,M. de la Torre-Juárez,Ashwin R. Vasavada +16 more
TL;DR: In this article, the authors analyze the complete set of in-situ meteorological data obtained from the Viking landers in the 1970s to today's Curiosity rover to review their understanding of the modern near-surface climate of Mars, with focus on the dust, CO2 and H2O cycles and their impact on the radiative and thermodynamic conditions near the surface.

TL;DR: The Mars Science Laboratory Curiosity rover observations of the 2018/Mars year 34 global/planet-encircling dust storm represent the first in situ measurements of a global dust storm with dedicated meteorological sensors since the Viking Landers.

Hydration state of calcium sulfates in Gale crater, Mars: Identification of bassanite veins
William Rapin,William Rapin,P.-Y. Meslin,P.-Y. Meslin,Sylvestre Maurice,Sylvestre Maurice,D. T. Vaniman,Marion Nachon,N. Mangold,Susanne Schröder,Olivier Gasnault,Olivier Gasnault,Olivier Forni,Olivier Forni,Roger C.

TL;DR: In-situ analyses reveal the presence of hydrogen within calcium sulfate veins crosscutting the sediments found in Gale crater as mentioned in this paper, which is consistent with a hyperarid climate and favored by burial or impacts.
