A dynamic system to forecast ionospheric storm disturbances based on solar wind conditions

open access: yesAnnals of Geophysics, 2005
For the reliable performance of technologically advanced radio communications systems under geomagnetically disturbed conditions, the forecast and modelling of the ionospheric response during storms is a high priority.

On the Propagation of Traveling Ionospheric Disturbances From the Hunga Tonga‐Hunga Ha'apai Volcano Eruption and Their Possible Connection With Tsunami Waves

open access: yesGeophysical Research Letters, 2023
We report our analysis of ionospheric disturbances from the 15 January 2022 Tonga volcano eruption, using GPS data from the International GNSS Service network and ionosonde data in the Australian sector.

Statistical Study of F‐Region Short Period Ionospheric Disturbances Related to Convection in the Lower Atmosphere Over Wuhan, China

open access: yesSpace Weather, 2022
We investigated the relationship between convective activity and F‐region short‐period ionospheric disturbances at middle latitudes from 2018 to 2020. The ionospheric variations were extracted from the total electron content (TEC) data obtained by the ...

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

April 2000 geomagnetic storm: Ionospheric drivers of large geomagnetically induced currents [PDF]

open access: yes, 2003
International audienceGeomagnetically induced currents (GIC) flowing in technological systems on the ground are a direct manifestation of space weather. Due to the proximity of very dynamic ionospheric current systems, GIC are of special interest at high

Relation of Extreme Ionospheric Events with Geomagnetic and Meteorological Activity

open access: yesAtmosphere, 2022
This paper studies extreme ionospheric events and their relations with geomagnetic and meteorological activity. With the long observation series at the Irkutsk (52° N, 104° E) and Kaliningrad (54° N, 20° E) ionosondes we obtained the datasets of ...

Ionospheric response to the corotating interaction region-driven geomagnetic storm of October 2002 [PDF]

open access: yes, 2009
Unlike the geomagnetic storms produced by coronal mass ejections (CMEs), the storms generated by corotating interaction regions (CIRs) are not manifested by dramatic enhancements of the ring current. The CIR-driven storms are however capable of producing
