Composition of Titan's lower atmosphere and simple surface volatiles as measured by the Cassini-Huygens probe gas chromatograph mass spectrometer experiment

Atreya, S. K.; Lunine, J. I.; Kasprzak, W. T. +7 more

The Cassini-Huygens probe gas chromatograph mass spectrometer (GCMS) determined the composition of the Titan atmosphere from ∼140 km altitude to the surface. After landing, it returned composition data of gases evaporated from the surface. Height profiles of molecular nitrogen (N₂), methane (CH₄), and molecular hydrogen (H

A large fraction of the major unsaturated species (C₂H₂ C₂H₄, HCN, and HC₃N) with mixing ratios of about 3 × 10^-6, 10^-7-10^-8, 3 × 10^-7, and 10^-9-10^-10 reside in Titan's atmosphere between 150 and 500 km (Vinatier et al., 2009; C…
