Automated real time detection of solar wind shocks and consequences for the identification of SSC and SI events [PDF]

, 2005
Algorithms have been developed to automatically detect Earth bound shocks in the solar wind as measured by the ACE satellite. These involve simple threshold techniques and wavelet analysis.

Automated Detection of Equatorial Plasma Bubbles From the Magnetic Measurements of Macau Science Satellite‐1 Using Machine Learning

Space Weather, Volume 24, Issue 4, April 2026.
Abstract Equatorial plasma bubbles (EPBs) are plasma density depletion structures that produce magnetic field perturbations through the diamagnetic effect and therefore need to be identified and excluded in high‐precision geomagnetic field modeling. Traditional EPB detection methods typically rely on in situ electron density or total electron content ...

Global Impacts of Ultra‐Low‐Frequency Waves: 1. Thermospheric Responses and Traveling Atmospheric Disturbances

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract Ultra‐low‐frequency (ULF) waves cause local Thermosphere‐Ionosphere (T‐I) perturbations, but their impacts on the global T‐I system including the generation of Traveling Atmospheric Disturbances (TADs) have never been evaluated. The mechanisms responsible for the TAD generation and propagation, whether through dynamic or thermal process, are ...

Automated Coronal Hole Identification via Multi-Thermal Intensity Segmentation

, 2017
Coronal holes (CH) are regions of open magnetic fields that appear as dark areas in the solar corona due to their low density and temperature compared to the surrounding quiet corona.

Mesospheric and Lower Thermospheric Responses to the May 2024 Geomagnetic Storm in the Antarctic Peninsula

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract We analyze the response of mean winds and semidiurnal tides (SDTs) in the mesosphere and lower thermosphere (MLT; ∼70–110 km altitude) to the May 2024 geomagnetic super storm, based on meteor radar (MR) observations from King Sejong Station (KSS; geographic: 62.22°S, 58.78°W; geomagnetic: 53.27°S, 10.88°E) in the Antarctic Peninsula.

Influence of Pipeline Insulation Leakage Points on the Distribution of Geomagnetically Induced Current and Pipe-Soil Potential

IEEE Access, 2019
During geomagnetic storms, geomagnetically induced currents (GIC) and pipe-soil potential (PSP) generated in a pipeline present a risk to the safe operation of the pipeline.
