It is known that lightning-generated VLF waves, called whistlers, propagate into the Earth's magnetosphere along paths dictated by the local magnetic field strength and plasma density. Their sensitivity to plasma density has made them a valuable tool for remotely estimating the density in the magnetosphere. Optical measurement of lightning on Jupiter suggest that whistler should also be present in the Jovian magnetosphere, and Voyager 1 did detect them as it passed through. Plasma properties of the Jovian magnetosphere can be evaluated by analyzing whistler propagation and their dispersion on the spectrogram. In this study, we perform this task using a hot raytracing code HOTRAY. The dispersion of observed whistlers are analyzed by following the ray paths of these waves using a realistic analytical density model based on Voyager and Pioneer data. This is the first time the real paths are taken into account to analyze their dispersion. Thus, the equatorial electron density, proton concentration of the Io torus can be evaluated. In addition, constraints can be also placed on the inner plasmasphere plasma density for which there is little direct observational data. This study extends our knowledge of the Io torus as well as the inner plasmasphere.
