Abstract
This is the supporting data set for the paper by the same title published in AGU JGR Space Physics.
Key Points:
Upward-traveling electron loss-cone distribution together with counter-streaming electron beam and hot protons are detected in bKOM source region.
Kilometric emission is measured accompanied by ion-cyclotron frequency range emission and weak whistler mode-like signature.
The observed wave spectra and particle characteristics are modeled by employing quasilinear wave-particle analysis.
Abstract
Jovian broadband kilometric emission (bKOM) is observed by the Juno spacecraft within a source region in the northern hemisphere near the equatorward edge of the auroral oval. A well-developed upward loss cone is the free-energy source of the bKOM. The spacecraft also detected intense low-energy (few hundred eV) counter-streaming electrons which are known to generate whistler mode emission via Landau resonance. In addition, hot protons (tens of keV thermal energy) accompanied by Alfvénic low-frequency emissions are also frequently detected in these source regions. We use quasilinear analysis to examine the generation and growth of bKOM and the dynamics of wave-particle interaction of the electron beams with bKOM and the growth of whistler mode and Z-mode emission. We also carry out quasilinear analysis of protons interacting with the low-frequency modes that coexist in the bKOM source region. The comprehensive quasilinear wave-particle analysis involving the energetic loss-cone electrons and high-frequency bKOM emission; counter-streaming electron beams and low-frequency/low-intensity electrostatic modes, and hot protons and Alfvén/proton-cyclotron wave emission, are shown to be quite successful in explaining/replicating the observed wave emission characteristics and various charged-particle properties.
