GLONASS Observation of Artificial Field‐Aligned Plasma Irregularities Near Magnetic Zenith During EISCAT HF Experiment
; ; (Geophysical Research Letters, 2021-02-22)
We report on simultaneous observation of artificial plasma density irregularities near the magnetic zenith (MZ) by incoherent scatter radar and GNSS satellite in the high latitude. During an EISCAT (European Incoherent ... -
Impact of Martian Crustal Magnetic Field on the Ion Escape
; ; ; Woch, J.; McFadden, J.; ; ; ; (Journal of Geophysical Research: Space Physics, 2020)
Based on the Mars Atmosphere and Volatile EvolutioN (MAVEN) observations, we have analyzed the role of the crustal magnetic field on ion loss driven by the direct interaction of the solar wind with the Mars ionosphere. ... -
Induced Magnetic Fields and Plasma Motions in the Inner Part of the Martian Magnetosphere
; ; ; ; ; ; ; ; ; ; ; ; (Journal of Geophysical Research: Space Physics, 2021-12-27)
Analysis of Mars Atmosphere and Volatile Evolution (MAVEN)/Supra‐Thermal And Thermal Ion Composition observations in the Martian upper atmosphere, bounded at higher altitudes by the shocked solar wind, shows that the draping ... -
Intercalibration of the Plasma Density Measurements in Earth's Topside Ionosphere
; ; ; ; ; ; ; ; ; ; (Journal of Geophysical Research: Space Physics, 2021-10-06)
Over the last 20 years, a large number of instruments have provided plasma density measurements in Earth's topside ionosphere. To utilize all of the collected observations for empirical modeling, it is necessary to ensure ... -
L‐Band Synthetic Aperture Radar Observation of Ionospheric Density Irregularities at Equatorial Plasma Depletion Region
; ; ; ; ; (Geophysical Research Letters, 2021-08-23)
Plasma density irregularities in the equatorial ionosphere are thought to cause the distortions of L‐band Synthetic Aperture Radar (SAR) images, which have been observed in recent years, but the origin of the image distortion ... -
September 2019 Antarctic Sudden Stratospheric Warming: Quasi-6-Day Wave Burst and Ionospheric Effects
; ; ; ; Siddiqui, T.; Kervalishvili, G.; Laštovi?ka, J.; Kozubek, M.; Ward, W.; Themens, D. R.; Kristoffersen, S.; (Geophysical Research Letters, 2020)
An exceptionally strong stationary planetary wave with Zonal Wavenumber 1 led to a sudden stratospheric warming (SSW) in the Southern Hemisphere in September 2019. Ionospheric data from European Space Agency's Swarm satellite ... -
Solar Activity Driven 27‐Day Signatures in Ionospheric Electron and Molecular Oxygen Densities
; (Journal of Geophysical Research: Space Physics, 2022-09-13)
The complex interactions in the upper atmosphere, which control the height‐dependent ionospheric response to the 27‐day solar rotation period, are investigated with the superposed epoch analysis technique. 27‐day signatures ... -
The Delayed Ionospheric Response to the 27‐day Solar Rotation Period Analyzed With GOLD and IGS TEC Data
; ; (Journal of Geophysical Research: Space Physics, 2021-02-07)
The delayed ionospheric response is analyzed for two well‐defined 27‐day solar rotation periods in the year 2019 with solar radio flux index F10.7 and Global‐scale Observations of the Limb and Disk (GOLD) data, like solar ... -
The Height‐Dependent Delayed Ionospheric Response to Solar EUV
; ; ; (Journal of Geophysical Research: Space Physics, 2022-03-24)
Based on the analysis of electron density Ne profiles (Grahamstown ionosonde), a case study of the height‐dependent ionospheric response to two 27‐day solar rotation periods in 2019 is performed. A well‐defined sinusoidal ... -
The Mini Induced Magnetospheres at Mars
; ; ; ; ; (Geophysical Research Letters, 2023-02-08)
We report on observations made by the Mars Atmosphere and Volatile EvolutioN spacecraft at Mars, in the region of the ion plume. We observe that in some cases, when the number density of oxygen ions is comparable to the ...
