The Real‐Time Advanced Ionospheric Data Assimilation (AIDA) Model
Space WeatherThe Advanced Ionospheric Data Assimilation (AIDA) is a real‐time data assimilation model of global 3D ionosphere and plasmasphere electron density. Changes in the local space environment can occur on very short timescales, particularly during disturbed ...

Premidnight plasmaspheric “plumes” [PDF]
Journal of Geophysical Research: Space Physics, 1997 To explain observations of brief intervals of cold, dense plasma by geosynchronous satellites in the midnight sector prior to or during substorm onset, it has recently been proposed that dense plasmaspheric plasma is drawn out to geosynchronous orbit in the premidnight region by inductive electric fields during the growth phase of a geomagnetic ...

PINE-RT: An operational real-time plasmasphere model
Frontiers in Astronomy and Space Sciences, 2023 The plasmasphere is a region of cold and dense plasma around the Earth, corotating with the Earth. Its plasma density is very dynamic under the influence of the solar wind and it influences several processes such as the GPS navigation, the surface ...

A plasmaspheric cavity resonance in a longitudinally non-uniform plasmasphere [PDF]
Earth, Planets and Space, 2014 Power spectra of a plasmaspheric cavity resonance (strictly, a plasmaspheric virtual resonance) in a longitudinally non-uniform plasmasphere are calculated. It is shown that the spectra depend on longitude. Therefore, a cavity resonance mode can have local time depending spectra when the plasmasphere is non-uniform in a longitudinal direction.

Formation of the oxygen torus in the inner magnetosphere: Van Allen Probes observations [PDF]
, 2015 We study the formation process of an oxygen torus during the 12–15 November 2012 magnetic storm, using the magnetic field and plasma wave data obtained by Van Allen Probes.

Frontiers in Astronomy and Space Sciences, 2023 Hiss waves play an important role in removing energetic electrons from Earth’s radiation belts by precipitating them into the upper atmosphere. Compared to plasmaspheric hiss that has been studied extensively, the evolution and effects of plume hiss are ...

The trapping of equatorial magnetosonic waves in the Earth’s outer plasmasphere [PDF]
, 2014 We investigate the excitation and propagation of equatorial magnetosonic waves observed by the Van Allen Probes and describe evidence for a trapping mechanism for magnetosonic waves in the Earth\u27s plasmasphere.

Internal source of plasmaspheric hiss on Earth
地球与行星物理论评, 2022 Plasmasphere is an upward extension of the ionosphere at low and middle latitudes along the closed magnetic field lines rooted in the Earth, where the trapped whistler-mode waves in the frequency range from tens to thousands of Hertz are named as ...
