英文摘要	Whistler mode waves are suggested to play a dual role in precipitation loss and acceleration of energetic electrons in Jovian magnetosphere. Using the combined wave data from Juno and Galileo, we constructed global maps of whistler mode waves in the Jovian inner magnetosphere (M-shell <20). Whistler mode waves are found to be extensively present over M-shells from 6 to ~13, peaking at ~10, and extend to magnetic latitudes at least up to 50°. Whistler mode wave intensities vary from a few pT to ~100 pT, similar to the intensity level at Earth. The new finding on the latitudinal extension of whistler mode waves indicates their potential effects on electron precipitation over a broad energy range from ~100 eV to several MeV. The newly constructed whistler mode wave spectra are crucial for evaluating the accurate role of whistler mode waves in energetic electron dynamics in the Jovian inner magnetosphere. ©2020.
