Enhancing Low‐Latitude Ionospheric Irregularity Prediction With Generalized Linear Models

Space Weather, Volume 24, Issue 3, March 2026.
Abstract The ionosphere poses challenges for accurate forecasting due to its complexity and variability. Irregularities in the lower ionosphere are influenced by local time, season, geographic location, solar activity and space weather, complicating precise predictions.

Long-Term Variations of Plasmaspheric Total Electron Content from Topside GPS Observations on LEO Satellites

Remote Sensing, 2021
The plasmasphere is located above the ionosphere with low-energy plasma, which is an important component of the solar-terrestrial space environment. As the link between the ionosphere and the magnetosphere, the plasmasphere plays an important role in the

Analysis of plasmaspheric hiss wave amplitudes inferred from low-altitude POES electron data: Technique sensitivity analysis [PDF]

, 2015
A novel technique capable of inferring wave amplitudes from low-altitude electron measurements from the Polar Operational Environmental Satellites (POES) spacecraft has been previously proposed to construct a global dynamic model of chorus and ...

Quiet‐Time Equatorial Ionization Anomaly Reversal Observed by the Satellites of Defense Meteorological Satellite Program (DMSP) and Ionospheric Connection Explorer (ICON)

Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract We investigated the quiet‐time temporal variations of the Equatorial Ionization Anomaly (EIA) and underlying plasma fountain observed in the topside ionosphere during the various F‐region equatorial E × B drift events recorded by the Jicamarca Incoherent Scatter Radar and simulated by SAMI3.

Monitoring Space Weather: Using Automated, Accurate Neural Network Based Whistler Segmentation for Whistler Inversion

Space Weather, 2022
It is challenging, yet important, to measure the—ever‐changing—cold electron density in the plasmasphere. The cold electron density inside and outside of the plasmapause is a key parameter for radiation belt dynamics.

Cause of plasmasphere corotation lag [PDF]

Geophysical Research Letters, 2004
It is hypothesized that the recently observed plasmasphere corotation lag is caused by a corresponding corotation lag in the upper ionosphere. Rotation rates of long‐lived plasmaspheric notches are compared to ionospheric drifts observed on DMSP spacecraft in the same longitude sectors.

Climatology of Equatorial Plasma Bubbles: Role of Gravity Wave Seeding and Ionospheric Preconditioning

Space Weather, Volume 24, Issue 3, March 2026.
Abstract This study investigates the linkage between mesopause gravity waves and equatorial plasma bubbles (EPBs) from 2012 to 2015 using the collocated nightglow measurements, O2 (762 nm) and OI (630 nm), observed by the Visible and near‐Infrared Spectral Imager onboard the International Space Station under the Ionosphere, Mesosphere, upper Atmosphere,

Spatial Distribution and Plasmaspheric Ducting of Auroral Kilometric Radiation Revealed by Wind, Polar, and Arase

AGU Advances
Auroral Kilometric Radiation (AKR), the dominant radio emission from Earth, has been extensively studied, though previous analyses were constrained by limited spacecraft coverage.

A Statistical Model of Inner Magnetospheric Electron Density: Van Allen Probes Observations

Space Weather, 2022
Based on electron density observations between September 2012 and July 2019 from the Electric and Magnetic Field Instrument Suite and Integrated Science (EMFISIS) on board the Van Allen Probes (VAPs) spacecraft, this paper makes a statistical ...
