Scientific paper

Because of a lack of readily usable information pertaining to the polarization of the Voyager 1 and 2 high-frequency band data, a technique has been developed that aids the identification of Io-dependent decametric radiation originating from the southern hemisphere of Jupiter. This technique compares the results of model ray tracing calculations with the Planetary Radio Astronomy (PRA) observations. A large portion of the Voyager 1 and 2 PRA observations are sorted into bins (±3° wide) centered on a specific Io central meridian longitude. When the data are plotted (as a frequency-longitude spectrogram) in this coordinate system, Io-dependent features can be identified and compared with ray tracing calculations performed in a model Jovian magnetosphere where it is assumed that the decametric emissions are generated in the RX mode from low-altitude source regions along the instantaneous Io flux tube. Two different magnetic field models are used, and the results are contrasted. In this study, the authors compare the observations for constant sub-Io longitudes of 260° and 300° with the corresponding model ray tracings.
