This is the dataset for.the paper "Generation and Impacts of Whistler-mode Waves during Energetic Electron Injections in Jupiter’s Outer Radiation Belt" submitted to Journal of Geophysical Research: Space Physics.Energetic particle injections are commonly observed in Jupiter’s magnetosphere and have important impacts on the radiation belts. We evaluate the roles of electron injections in the dynamics of whistler-mode waves and relativistic electrons using Juno measurements and wave-particle interaction modeling. The Juno spacecraft observed injected electron flux bursts at energies up to 300 keV at M shell ~11 near the magnetic equator during perijove-31. The electron injections are correlated with chorus wave bursts at 0.05-0.5 fce frequencies, where fce is the electron gyrofrequency. The electron pitch angle distributions are anisotropic, peaking near 90° pitch angle, and the fluxes are high during injections. We calculate the whistler-mode wave growth rates using the observed electron distributions and linear theory. The frequency spectrum of the wave growth rate is consistent with that of the observed chorus magnetic intensity, suggesting that the observed electron injections provide free energy to generate whistler-mode chorus waves. We further use quasilinear theory to model the impacts of chorus waves on 0.1-10 MeV electrons. Our modeling shows that the chorus waves could cause the pitch angle scattering loss of electrons at
