Space Weather Effects From Moderate to Severe Geomagnetic Storms in October 2024 Over the Latin American Sector

Space Weather, Volume 24, Issue 6, June 2026.
Abstract This study presents a detailed case study of the ionospheric impacts of moderate (G2) and severe (G4) geomagnetic storms over the Latin American sector, with particular emphasis on the formation and suppression of equatorial plasma bubbles (EPBs).

Pilot Ionosonde Network for Identification of Traveling Ionospheric Disturbances

, 2018
Traveling ionospheric disturbances (TIDs) are the ionospheric signatures of atmospheric gravity waves. Their identification and tracking is important because the TIDs affect all services that rely on predictable ionospheric radio wave propagation ...

Interrelation of traveling ionospheric disturbances above and below the F-layer peak according to the ionosonde and the SWARM constellation data

Учёные записки Казанского университета: Серия Физико-математические науки, 2019
One approach to determining the height structure of the mid-latitude medium-scale travelling ionospheric disturbances (MSTIDs) above the F layer peak is to involve simultaneous satellite measurements in the ground-based ionosonde measurements near Kazan.

ION-FAST as the NIRFI’s Ionospheric Diagnostic Platform

Atmosphere
In December 2021, we presented a prototype of a fast ionosonde for vertical sounding based on the usage of publicly available radio-electronic components. This approach led to a major reduction in the cost of the created device. We called our development

ROSE: a high performance oblique ionosonde providing new opportunities for ionospheric research

Annals of Geophysics, 1994
A high quality high frequency (HF) oblique ionosonde has been developed for use in propagation research and associated studies of the ionosphere. The ionosonde is known as ROSE (radio oblique sounding equipment) and requires the connection of a specially

Assessing PlanetiQ GNSS-RO Ionospheric Electron Density and TEC Using Ground-Based Ionosondes and COSMIC-2

Remote Sensing
Radio occultation (RO) has become a key technique for monitoring the ionosphere by deriving electron density (Ne) profiles and total electron content (TEC) from GNSS signals.

Realistic Ionosphere: real-time ionosonde service for ISWI

, 2018
Ionosondes have remained the main provider of continuous “ground-truth” observations of the subpeak ionospheric plasma density, available for assimilation in weather models with only a few minutes latency from the measurement.

Sensitivity of ionosonde detection of atmospheric disturbances induced by seismic Rayleigh waves at different latitudes

Earth, Planets and Space, 2017
Ionospheric disturbance was observed in ionograms at Kazan, Russia $$(55.85^\circ \hbox {N}, 48.81^\circ \hbox {E})$$(55.85∘N,48.81∘E), associated with the M8.8 Chile earthquake in 2010 $$(35.91^\circ \hbox {S}, 72.73^\circ \hbox {W})$$(35.91∘S,72.73∘W).
