Abstract
AbstractWhistler‐mode and Z‐mode waves may have significant impact on electron scattering and acceleration at Jupiter as recent stochastic models indicate. New observations of these waves in the Juno extended mission expand the orbital coverage from previous surveys, extending especially to smaller radial distances near the magnetic equator, and to extended ranges of dusk‐side magnetic local time. M‐shells transiting the Io torus and the orbit of Europa are recognized as a significant source region for whistler‐mode lower and upper band chorus emission with intensity peaks near 9 RJ. Ganymede is a significant source of intense whistler‐mode chorus confined to the local moon environment. New Z‐mode observations now extend from a few kHz to over 80 kHz. Inferred source regions for Z‐mode are consistent with the outer edge of the Io torus and with auroral field lines that may also support broadband kilometric or decametric emission.
