Data associated with the publication: Compositional measurements of Saturn's upper atmosphere and rings from Cassini INMS: An extended analysis of measurements from Cassini's grand finale orbits

These data include the cleaned mass spectra from Cassini INMS orbits 288, 290, 291, 292, and 293. This includes averaged mass spectra for each orbit as well as binned mass spectra that are divided into altitudinal regions to retrieve density profiles for species as detailed in the corresponding publication. The species fragmentation pattern database used for analysis and mixing ratio profile results are also included.
