Combined model of topside ionosphere and plasmasphere derived from radio-occultation and Van Allen Probes data [PDF]
Scientific Reports, 2022 In the last years, electron density profile functions characterized by a linear dependence on the scale height showed good results when approximating the topside ionosphere. The performance above 800 km, however, is not yet well investigated.

A novel neural network model of Earth’s topside ionosphere [PDF]
Scientific Reports, 2023 The Earth’s ionosphere affects the propagation of signals from the Global Navigation Satellite Systems (GNSS). Due to the non-uniform coverage of available observations and complicated dynamics of the region, developing accurate models of the ionosphere ...

The Effects of Solar Wind Dynamic Pressure on the Structure of the Topside Ionosphere of Mars
Geophysical Research Letters, 2019 We use Mars Atmosphere and Volatile EvolutioN observations of the upstream solar wind, and Mars Express observations of ionospheric electron densities and magnetic fields, to study how the topside ionosphere (>320 km) of Mars is affected by variations in

Dissipation of field-aligned currents in the topside ionosphere. [PDF]
Sci Rep, 2022 AbstractField-aligned currents (FACs) are electric currents parallel to the geomagnetic field and connecting the Earth’s magnetosphere to the high-latitude ionosphere. Part of the energy injected into the ionosphere by FACs is converted into kinetic energy of the surrounding plasma.

TEC Enhancement due to Energetic Electrons Above Taiwan and the West Pacific
Terrestrial, Atmospheric and Oceanic Sciences, 2013 The energetic electrons of the inner radiation belt during a geomagnetic disturbance can penetrate in the forbidden range of drift shells located at the heights of the topside equatorial ionosphere (< 1000 km).

Enhanced variability in the topside ionosphere
Annals of Geophysics, 1995 Variability of total electron content (TEC) observed by the Faraday rotation method at Florence has been stud- ied with the same technique applied independently to the ionospheric parameters foF2 and M(3000)F2 of the ground-based vertical-incidence ...

Modeling of Topside Ionosphere and Plasmasphere [PDF]
, 2021 Abstract We developed a new topside ionosphere and plasmasphere model using a machine learning technique using approximately five million electron density datasets from the Japanese satellites, namely, Hinotori, Akebono, and Arase. The topside ionosphere and plasmasphere model (TIP-model) can estimate electron densities at altitudes ranging ...

A New Method for Retrieving Electron Density Profiles from the MARSIS Ionograms
Remote Sensing, 2022 The Martian ionosphere was actively detected by Mars Advanced Radar for Subsurface and Ionosphere Sounding (MARSIS) aboard the Mars Express. The detected echo signal of the MARSIS at an epoch is presented as a function of frequency and time delay to form
