Simulation of Transient Topside Layer in the Martian Ionosphere
Remote Sensing, 2023 Many Mars missions, e.g., Mariner, Viking, Mars Global Surveyor (MGS), Mars Express (MEX), and Mars Atmosphere and Volatile Evolution (MAVEN), have been launched to study the Martian atmosphere.

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 ...

The Analysis of the Topside Additional Layer of Martian Ionosphere Using MARSIS/Mars Express Data [PDF]
Journal of Astronomy and Space Sciences, 2012 In this study, the transient second or third layer on the topside of the Martian ionosphere were investigated with the most recently released Mars advanced radar for subsurface and ionospheric sounding/Mars Express data obtained from January 2010 to ...

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

Is there a hole in the topside, equatorial ionosphere?
Results in Physics, 2016 A paper in 2000 (Huba, 2000) found a depression in electron density in the topside ionosphere near the magnetic equator, based on the SAMI-2 physical ionospheric model.

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

Triton: Topside ionosphere and nitrogen escape [PDF]
Geophysical Research Letters, 1990 The principal ion in the ionosphere of Triton is N+. Energetic electrons of magnetospheric origin are the primary source of ionization, with a smaller contribution due to photoionization. To explain the topside plasma scale height, we postulate that N+ ions escape from Triton. The loss rate is 3.4 × 107 cm−2 s−1 or 7.9 × 1024 ions s−1.

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2020 The analytical description of the topside ionosphere included in the NeQuick model is studied in detail. First, the modeled scale height behavior is analyzed at infinity and for the lowest part of the topside region; in the latter case, the analysis is ...
