A nearly universal solar wind-magnetosphere coupling function inferred from 10 magnetospheric state variables

, 2007
[1] We investigated whether one or a few coupling functions can represent best the interaction between the solar wind and the magnetosphere over a wide variety of magnetospheric activity.

Lightning‐Induced Electron Precipitation Events Observed at Low Altitudes

Journal of Geophysical Research: Space Physics, Volume 130, Issue 4, April 2025.
Abstract Lightning‐induced electron precipitation (LEP) events are important phenomena in the Earth's inner magnetosphere, where atmospheric lightning strokes cause energetic electron loss from the radiation belts. Lightning strokes generate electromagnetic waves that penetrate the ionosphere and propagate through the Earth's magnetosphere as so‐called

Geomagnetic storm simulation with a Coupled magnetosphere-ionosphere-thermosphere model

, 2013
We present the first global, self-consistent, fully electrically coupled magnetosphere-ionosphere-thermosphere model, based on the UCLA magnetosphere-ionosphere model and the NOAA Coupled Thermosphere Ionosphere Model (CTIM).

On the Relationship Between Solar Wind High‐Speed Stream Waves and Geomagnetic Pc5 Activity From Mid to High Latitudes: A Case Study on January 5‐12 2008

Journal of Geophysical Research: Space Physics, Volume 130, Issue 4, April 2025.
Abstract This study aims to investigate the possible influence of Alfvénic and compressive low‐frequency fluctuations in a solar wind corotating high‐speed stream on the geomagnetic activity from mid to high latitudes. We selected a stream in the declining phase of solar cycle 23, impinging on Earth's magnetosphere on 5–12 January 2008.

Estimating the effects of ionospheric plasma on solar wind/magnetosphere coupling via mass loading of dayside reconnection: Ion‐plasma‐sheet oxygen, plasmaspheric drainage plumes, and the plasma cloak

, 2013
Estimates are calculated for the storm time reduction of solar wind/magnetosphere coupling by the mass density ρm of the magnetospheric plasma. Based on the application of the Cassak‐Shay reconnection‐rate formula at the dayside magnetopause, a numerical

Modeling Jupiter's Dawnside Magnetodisc: Using Juno Observations to Constrain a Radial Force‐Balance Model

Journal of Geophysical Research: Space Physics, Volume 130, Issue 4, April 2025.
Abstract This study investigates Jupiter's dawnside magnetodisc, using plasma and magnetic field measurements from Juno orbits 5 to 12 to refine a radial force‐balance magnetodisc model. This iterative vector potential model examines variations in the azimuthal magnetodisc current, coupled with a magnetosphere‐ionosphere coupling model from which the ...

Data‐Driven Transfer Functions From Differential Magnetometer Measurements to Enhance GIC Model Validation Capability: A Case Study in the Spanish Power Grid

Space Weather, Volume 23, Issue 4, April 2025.
Abstract Geomagnetically induced currents (GICs) are unwanted currents flowing in long grounded conductors because of space weather phenomena. Example GICs are those flowing in power transmission lines via grounded transformer neutrals. Prediction models, used to foresee the amplitudes and waveforms of those currents and to identify weak points in ...

The Magnetosphere‐Ionosphere‐Ground Responses to the May 2024 Super Solar Storm

Space Weather, Volume 23, Issue 4, April 2025.
Abstract Earth suffered the attack of the strongest geomagnetic storm in the last 20 years (Kp = 9, Dst∼ ${\sim} $ −400 nT) occurred on 11 May 2024. Taking advantage of the LEO multi‐parameter CSES satellite (launched in 2018) with a large inclination angle 97° $97{}^{\circ}$, with the joint observations of NOAA and GOES, we present a comprehensive ...
