| Abstract: | Local electromagnetic and hydromagnetic noise in the Jovian magnetosphere is expected to be intense due to the variety of wave-particle interactions and plasma instabilities that may be present. In order to qualitatively assess the nature of the radio noise, configuration space analogues of the well-known Clemmow-Mullaly-Allis (CMA) propagation diagrams have been prepared, based on recent models of the magnetic field and plasma density. These diagrams identify the loci of electron and ion resonances and cutoffs where absorption and reflection of wave energy occur, and specify the propagation modes and frequency bands that are anticipated in various regions. Such information may guide the selection of wave detection instruments, influence the choice of flyby trajectories, and assist in the interpretation of measurements. |
