Volume Mixing Ratios of Major Atmospheric Components on Mars as Measured by MSL/SAM

Averaged instantaneous mixing ratios for major gases on Mars as measured by the Sample Analysis at Mars (SAM) instrument suite on Mars Science Laboratory. Raw data used to generate this dataset are freely available on NASA's Planetary Data System (PDS) Geosciences Node, from within six months after receipt on Earth (http://pds-geosciences.wustl.edu/missions/msl/). SAM data used are Reduced Data Records (RDR), Level 1A. Data have been processed using calibration approach described in: Franz et al., Franz, H. B., et al. (2017), Initial SAM calibration gas experiments on Mars: Quadrupole mass spectrometer results and implications, Planet. Space Sci., 138, 44-54, doi:10.1016/j.pss.2017.01.014. Franz, H. B., et al.
