Identification of Locally Generated Plasmaspheric Hiss
Abstract In this study, we statistically analyze the wave properties of plasmaspheric hiss using data from the Van Allen Probes. The magnetic power spectral densities of hiss waves exhibit dependence on magnetic local time, geomagnetic activity, and the L‐shell. Based on variations in wave propertie...

| description | Abstract In this study, we statistically analyze the wave properties of plasmaspheric hiss using data from the Van Allen Probes. The magnetic power spectral densities of hiss waves exhibit dependence on magnetic local time, geomagnetic activity, and the L‐shell. Based on variations in wave properties—including normal angle, electromagnetic planarity, and the net Poynting flux direction Rs—with L‐shell and normalized frequency (the ratio of wave frequency to electron cyclotron frequency), hiss waves are categorized into four distinct regions. Waves with frequencies above 0.1fce exhibit characteristics of locally generated plasmaspheric hiss. Furthermore, the statistical distribution of suprathermal electron fluxes shows that the upper energy of injected energetic electrons matches well with the minimum resonant energy corresponding to the lower frequency of locally generated hiss. This study identifies locally generated hiss waves, which are well supported by the electron distributions. |
