Data associated with publication “Compositional Measurements of Saturn’s Upper Atmosphere and Rings from Cassini INMS” in the Journal of Geophysical Research: Planets.

These data comprise the end-products of our analyses. This includes the cleaned Cassini INMS mass spectrum from orbits 288, 290, 291, 292, and 293 for m/z 1 to 20 amu. The inbound density profiles of H2, He, CH4, H2O, and NH3 as well as the averaged mixing ratios of CH4, H2O, and NH3 are also included.
