In situ and ground-based intercalibration measurements of plasma density at l = 2.5 [PDF]

open access: yes, 2003
[1] Two independent ground-based experiments and two satellite-borne experiments are used to interpret the changes in plasmaspheric composition at the same point in space during moderate geomagnetic activity on 22 January and 14 February 2001.

The Micro‐Broadband Receiver (μBBR) on the Very‐Low‐Frequency Propagation Mapper CubeSat

open access: yesEarth and Space Science, 2021
The very low frequency (VLF) propagation mapper (VPM) is a 6U CubeSat designed to measure VLF radio waves in Low‐Earth Orbit. The science goals of the VPM mission are to measure VLF signals broadcast by the DSX mission, and to study natural and ...

The Effect of the Thermosphere on Ionosphere Outflows

open access: yesFrontiers in Astronomy and Space Sciences, 2021
The Naval Research Laboratory (NRL) Sami2 is Another Model of the Ionosphere (SAMI2) and Sami3 is Also a Model of the Ionosphere (SAMI3) ionosphere/plasmasphere codes have shown that thermosphere composition and winds significantly affect H+ outflows ...

Monitoring the plasmapause using geomagnetic field line resonances [PDF]

open access: yes, 2004
This paper discusses the use of ground magnetometer data to derive plasma mass density profiles of the dayside plasmapause region with spatial and temporal resolution in the range 0.15-0.4 R-E and 20-60 min.

New formulation for the topside ionosphere and plasmasphere based on NeQuick

open access: yesJournal of Space Weather and Space Climate
The total electron content (TEC) affecting signal propagation of Global Navigation Satellite Systems (GNSS) is strongly influenced by the topside ionosphere and plasmasphere. This study introduces a new approach to representing the two regions.

PINE-RT: An operational real-time plasmasphere model

open access: yesFrontiers 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 ...

Estimated plasmasphere electron content and O⁺/H⁺ transition height during the February 2022 geomagnetic storm from Irkutsk IS radar data

open access: yesSolar-Terrestrial Physics
We study the topside ionosphere above the NmF2 ionization maximum and the transition region between the ionosphere and the plasmasphere. We analyze the interaction between the topside ionosphere and the plasmasphere during a strong geomagnetic storm in ...

Deep learning model of hiss waves in the plasmasphere and plumes and their effects on radiation belt electrons

open access: yesFrontiers 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 ...

Photoelectron Flux Buildup in the Plasmasphere [PDF]

open access: yes, 1978
Processes which confine photoelectrons to the plasmasphere (e.g., collisional backscattering from the thermosphere and magnetic trapping due to pitch angle redistribution through Coulomb collisions in the plasmasphere) tend to increase the steady state ...

Internal source of plasmaspheric hiss on Earth

open access: yes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 ...
