In this thesis I present an in-depth study of the distribution of various neutral species in Titan's upper atmosphere, at altitudes between 950 and 1, 500 km for abundant species (N2, CH4 as well as their isotopes) and between 950 and 1, 200 km for most minor species. However, the study of the H2 distribution on Titan is extended to an altitude as high as 6, 000 km in the exosphere. The analysis is based on a large sample of Cassini/INMS (Ion Neutral Mass Spectrometer) measurements in the CSN (Closed Source Neutral) mode, obtained during 15 close flybys of Titan.The thermospheric dynamics on Titan may also be driven by its interactions with Saturna#39;s corotating plasma, which could deposit significant energy in Titana#39;s upper atmosphere through electron/ion precipitation with a pattern ...
