On the Upwelling of the F Layer Base and Prediction of Equatorial Plasma Bubble
Geophysical Research Letters, 2023 Prediction of equatorial plasma bubbles (EPBs) continues to be a challenge for the scientific community. We present a novel data analysis approach, employed on the collocated radar and ionosonde observations from Gadanki, providing new experimental ...

Вісник Харківського національногоуніверситету імені В.Н. Каразіна. Серія: Радіофізика та електроніка, 2021 Background. Ionospheric effects from solar eclipses (SEs) have been studied for over a century. The studies intensified in the 1960–1970, when rockets, satellites, ionosonde networks, and incoherent scatter radars became actively involved in the ...

Analysis of the Relation Between Solar Activity and Parameters of the Sporadic E Layer
AtmosphereBased on the ionosonde data from stations at different latitudes in high- and low-solar-activity years, the effects of solar activity on the parameters of the Es layer and the foE amplitude spectrum are analyzed.

Bayesian statistical ionospheric tomography improved by incorporating ionosonde measurements [PDF]
Atmospheric Measurement Techniques, 2016 We validate two-dimensional ionospheric tomography reconstructions against EISCAT incoherent scatter radar measurements. Our tomography method is based on Bayesian statistical inversion with prior distribution given by its mean and covariance. We employ

Seasonal Transitions in the Thermosphere Inferred from Ionospheric Observations
Remote Sensing, 2023 Ionospheric observations along with CHAMP/STAR neutral gas density measurements were used to retrieve thermospheric parameters and to check whether the equinox transition season exists separately from the December solstice and June solstice seasons ...

Ionospheric drift measurements with ionosondes
Annals of Geophysics, 1998 In the last forty years many attempts have been made to measure ionospheric plasma motions with HF radio sounders, generally specialized ionosondes. Starting in the 1950's, the so-called similar fading and the correlation methods were applied to estimate the velocities in the ionosphere.

Validation of CSES RO measurements using ionosonde and ISR observations
, 2020 The radio occultation (RO) measurements obtained by GOR payload on board the CSES (the first China Seismo-Electromagnetic Satellite) satellite are validated using the observations from five ionosonde stations located at different latitudes and one ...

IEEE Transactions on Geoscience and Remote Sensing, 2019 A new tomographic method was developed with the main goal of mapping the ionosphere in the region of Brazil. The ionospheric background was estimated based on ionosonde and radio-occultation measurements to overcome the lack of data provided by ...

Earth and Space Science, Volume 13, Issue 8, August 2026.Abstract A set of fresh Equatorial Plasma Bubbles (EPBs) formed during pre‐sunrise hours in the Southeast Asian sector amid the recovery phase of May 2024 geomagnetic storm. They offered new insights into their formation mechanism. This study used Total Electron Content (TEC) and Rate of TEC Index maps over Indonesia, along with ionosondes in Thailand ...
