“…Recent ray trace modeling has shown that hiss originates from a subset of chorus emissions that avoid Landau damping during propagation from the equatorial source region to higher latitude. Such waves also propagate to lower L where they enter and are trapped within the plasmasphere, where the discrete chorus emissions merge together to form incoherent hiss (Bortnik et al 2008b(Bortnik et al , 2009a. The unexpected association between hiss and chorus has been confirmed by simultaneous observations on two THEMIS spacecraft ) and differences in the statistical MLT distribution of the two emissions has been explained by 3D ray tracing (Chen et al 2009b).…”

The Electric and Magnetic Field Instrument and Integrated Science (EMFISIS) investigation on the NASA Radiation Belt Storm Probes (now named the Van Allen Probes) mission provides key wave and very low frequency magnetic field measurements to understand radiation belt acceleration, loss, and transport. The key science objectives and the contribution that EMFISIS makes to providing measurements as well as theory and modeling are described. The key components of the instruments suite, both electronics and sensors, including key functional parameters, calibration, and performance, demonstrate that EMFI-SIS provides the needed measurements for the science of the RBSP mission. The EMFISIS operational modes and data products, along with online availability and data tools provide the radiation belt science community with one the most complete sets of data ever collected.

In this work, Van Allen Probes data are used to derive terrestrial plasmaspheric hiss wave power distributions organized by (1) distance away from the plasmapause and (2) plasmapause distance from Earth. This approach is in contrast to the traditional organization of hiss wave power by L parameter and geomagnetic activity. Plasmapause‐sorting reveals previously unreported and highly repeatable features of the hiss wave power distribution, including a regular spatial distribution of hiss power with respect to the plasmapause, a standoff distance between peak hiss power and the plasmapause, and frequency‐dependent spatial localization of hiss. Identification and quantification of these features can provide insight into hiss generation and propagation and will facilitate improved parameterization of hiss wave power in predictive simulations of inner magnetosphere dynamics.

“…Although a variety of electromagnetic "hisses" have been observed with ground-based instruments and reported in the literature starting in the late 1950s [e.g., Ellis, 1959] (see reviews by Hayakawa and Sazhin [1992] and Bortnik et al [2009a]), it is important to distinguish PH as an emission that is only observed in space; that is, it was discovered and observed with the first high-altitude spacecraft [Dunckel and Helliwell, 1969;Russell et al, 1969] and named "plasmaspheric hiss" in large part due to its in situ measurement within the plasmasphere . This distinction is necessary because the PH observed in space is fairly well ordered, whereas the hiss observed at a given point on the ground is a superposition of electromagnetic wave energy that arrives from different sources on the ground and in space.…”
