Insights on Lightning‐Induced Remanent Magnetization From High‐Current Impulse Experiments

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 7, July 2026.
Abstract Lightning strikes generate intense transient magnetic fields capable of inducing strong and complex remanent magnetizations in rocks, potentially overprinting their original paleomagnetic record. To investigate the mechanisms and outcomes of lightning‐induced remanent magnetization, we conducted controlled high‐current impulse experiments on ...

Satellite Traces: Ionogram Signatures of Bottom‐Side Upwelling Structures ‐ A Simulation Study

Geophysical Research Letters
Satellite Traces (STs) are the important ionogram signatures for the presence of upwellings in the bottom‐side ionosphere, which provide the necessary seed perturbation for the development of equatorial plasma bubbles (EPBs).

Feasibility of geomagnetic localization and geomagnetic RatSLAM

, 2014
Abstract: The need for accurate indoor localization increases as we get used to accessible outdoor localization, and the number of applications depending on localization grows. Indoor localization is challenging because of frequent line of sight obstructions and dynamic changes in the environment.
