The Voyager and Galileo missions allowed the Jovian magnetospheric hot ion plasma to be measured and analyzed by instruments capable of determining spectral parameters of the populations and the bulk convection of the plasma magnetodisk and magnetotail. The Voyager 2 inbound [dayside] data was used to derive hot ion temperatures that increased with corotation energy (sulfur/oxygen) but remained nearly constant for hydrogen ions. Galileo orbital data in the nightside region, however, was examined using a 3 species model to extract temperatures, velocity, and other parameters. In this case the temperatures of all 3 species fell adiabatically with increasing distance, suggesting adiabatic cooling is occurring (given outward transport). At Saturn, the Cassini mission has enabled similar [but more detailed] measurements to be completed, from which convection and spectral features have been calculated. Here, both dominant species (hydrogen and oxygen) have nearly constant temperature in the middle to outer regions, although hot hydrogen ions appear to be heated adiabatically in the inner region. We use a recently completed convection study and analysis of spectral properties at various distances and local times to examine the transport and energization of magnetodisk plasma in the Saturnian magnetosphere. We also re-examine the Voyager and Galileo results with improved techniques and in-flight recalibrated passbands/efficiencies. The plasma convection patterns at Jupiter and Saturn are remarkably similar when scaled to the magnetopause distance. We examine the relationship between this convection and processes energizing the hot plasma in both Jupiter and Saturn's magnetospheres.
