Bridging the Gap Between the Earth's Ionosphere and Plasmasphere

Geophysical Research Letters, Volume 52, Issue 23, 16 December 2025.
Abstract Cold plasma distribution in the ionosphere‐plasmasphere system governs wave‐particle interactions, plasma energization and loss, and radio wave propagation. A longstanding observational gap at altitudes ∼ ${\sim} $800–8,000 km has largely prevented studying the coupled dynamics of the two regions.

A density-temperature description of the outer electron radiation belt during geomagnetic storms [PDF]

, 2009
Bi-Maxwellian fits are made to energetic-electron flux measurements from seven satellites in geosynchronous orbit, yielding a number density (n) and temperature (T) description of the outer electron radiation belt.

A Personal Voyage Among Earth and Space Physics Disciplines

Perspectives of Earth and Space Scientists, Volume 6, Issue 1, December 2025.
Abstract I have organized my thoughts in an autobiographical way in relation to the several distinct phases of my career encompassing Earth and space physics. I discuss atmospheric and space physics topics of interest to me in an international context, and I emphasize the value of community activities and international conferences for the interchange ...

A new electron density model of the plasmasphere for operational applications and services

Journal of Space Weather and Space Climate, 2018
The Earth's plasmasphere contributes essentially to total electron content (TEC) measurements from ground or satellite platforms. Furthermore, as an integral part of space weather, associated plasmaspheric phenomena must be addressed in conjunction with ...

Automatic Detection of Lightning Whistlers Observed by the Plasma Wave Experiment Onboard the Arase Satellite Using the OpenCV Library

Remote Sensing, 2019
The automatic detection of shapes or patterns represented by signals captured from spacecraft data is essential to revealing interesting phenomena. A signal processing approach is generally used to extract useful information from observation data.

Plasmatrough exohiss waves observed by Van Allen Probes: Evidence for leakage from plasmasphere and resonant scattering of radiation belt electrons [PDF]

, 2015
Exohiss waves are whistler mode hiss observed in the plasmatrough region. We present a case study of exohiss waves and the corresponding background plasma distributions observed by the Van Allen Probes in the dayside low-latitude region.

Refilling of the Earth's plasmasphere

Eos, Transactions American Geophysical Union, 1991
The Earth's ionosphere at mid‐latitudes is produced chiefly by solar EUV‐induced photo‐ionization of the neutral atmosphere at altitudes of 90 to 300–400 kilometers. Such ionized gas, or plasma—entrained by the Earth's (basically bipolar) magnetic field—flows upward along magnetic lines of force, until the plasma gas pressure is equalized along the ...
