Van Allen Probes Observations of Symmetric Stormtime Compressional ULF Waves. [PDF]
J Geophys Res Space Phys, 2022 AbstractPrevious spacecraft studies showed that stormtime poloidal ultralow‐frequency (ULF) waves in the ring current region have an antisymmetric (second harmonic) mode structure about the magnetic equator. This paper reports Van Allen Probes observations of symmetric ULF waves in the postnoon sector during a moderate geomagnetic storm.

Combined model of topside ionosphere and plasmasphere derived from radio-occultation and Van Allen Probes data [PDF]
Scientific Reports, 2022 In the last years, electron density profile functions characterized by a linear dependence on the scale height showed good results when approximating the topside ionosphere. The performance above 800 km, however, is not yet well investigated.

Propagation and Dispersion of Lightning-Generated Whistlers Measured From the Van Allen Probes [PDF]
Frontiers in Physics, 2021 We study the propagation and attenuation of lightning-generated whistler (LGW) waves in near-Earth space (L ≤ 3) through the statistical study of three specific quantities extracted from data recorded by NASA’s Van Allen Probes mission, from 2012 to 2019:

Local Generation of High‐Frequency Plasmaspheric Hiss Observed by Van Allen Probes [PDF]
Geophysical Research Letters, 2019 The generation of a high‐frequency plasmaspheric hiss (HFPH) wave observed by Van Allen Probes is studied in this letter for the first time. The wave has a moderate power spectral density (∼10−6 nT2/Hz), with a frequency range extended from 2 to 10 kHz ...

VLF waves from ground‐based transmitters observed by the Van Allen Probes: Statistical model and effects on plasmaspheric electrons [PDF]
Geophysical Research Letters, 2017 Whistler mode very low frequency (VLF) waves from powerful ground‐based transmitters can resonantly scatter energetic plasmaspheric electrons and precipitate them into the atmosphere.

Specifying High Altitude Electrons Using Low‐Altitude LEO Systems: Updates to the SHELLS Model
Space Weather, 2023 We describe a new version of the SHELLS model, which specifies the outer electron belt environment as observed by the Van Allen Probes using the Kp Index and data from Polar‐orbiting Operational Environmental Satellites and the Meteorological Operational
