The plasmasphere and advances in plasmaspheric research

Journal of Atmospheric and Solar-Terrestrial Physics, 2000
Abstract A review is made of recent major advances in plasmaspheric research; important results have emerged from those concerning a variety of plasmasphere features. Both experiments and modeling efforts have progressed. A number of unknowns still persist, however, but research is underway toward their clarification.

The dayside of the plasmasphere

Journal of Geophysical Research, 1971
The concentrations of H(+) ions in the dayside region of the plasmasphere, measured from March 1968 through February 1969 by the Lockheed light-ion mass spectrometer aboard the OGO 5 satellite, are presented and analyzed. The position of the plasmapause on the dayside appears to be determined by the level of magnetic activity present during the ...

Modeling the plasmasphere with SAMI3 [PDF]

open access: yesGeophysical Research Letters, 2013
The study of the plasmasphere is extremely important to understanding space weather phenomena; for example, it plays a critical role in the regulation of radiation belt dynamics. In this paper, the first 3D simulation of the plasmasphere based on the first‐principles physics model SAMI3 is presented.

The dynamic plasmasphere

Advances in Space Research, 1997
Abstract The outer plasmasphere is highly structured and very dynamic across a broad range of time and length scales. This is due to the interplay between refilling on the dayside and the erosion of the outer plasmasphere caused by variable magnetospheric convection.

Whistlers observed outside the plasmasphere: Correlation to plasmaspheric/plasmapause features

Journal of Geophysical Research: Space Physics, 2015
AbstractWhistlers observed outside the plasmasphere by Cluster have been correlated with the global plasmasphere using Imager for Magnetopause‐to‐Aurora Global Exploration‐Extreme Ultraviolet Imager (IMAGE‐EUV) observations. Of the 12 Cluster‐observed whistler events reported, EUV is able to provide global imaging of the plasmasphere for every event ...

Jovian plasmaspheres

Journal of Geophysical Research: Space Physics, 1978
Plasmaspheres within the Jovian magnetosphere can arise from three distinct types of processes: (1) by a photoelectron (positive ion) flux from the planetary ionosphere (the source type of earth's plasmasphere), (2) by ionization of the atmospheres and neutral particle tori of the satellites, and (3) by ionization of the neutral interstellar medium ...

The corotation of the plasmasphere

Journal of Atmospheric and Terrestrial Physics, 1976
Abstract It is shown that the plasmasphere corotates because of the high conductivity of the ionosphere. Because the conductivity of the ionosphere is greater during the day, there is a different response of the plasmapause (to a magnetic storm) on the night and day sides.

The Earth's Plasmasphere

1998
This is the first monograph to describe the historical development of ideas concerning the plasmasphere by the pioneering researchers themselves. The plasmasphere is a cold thermal plasma cloud encircling the Earth, terminating abruptly at a radial distance of 30,000 km over a sharp discontinuity known as the plasmapause.
