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

open access: yesJournal 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 ...

Distributed computing for the reconstruction of multi‐terabyte tomographic X‐ray imaging datasets

open access: yesJournal of Synchrotron Radiation, Volume 33, Issue 4, Page 1103-1109, July 2026.
As tomographic datasets from synchrotrons continue to increase in volume, so rises the challenge of reconstructing said data. Here we present a solution utilizing high‐performance computing capabilities to split the process into multiple smaller tasks, which can be solved without overwhelming a single compute node.

Modeling of Elves Doublets Based on Variations of the Lightning Return Stroke Current

open access: yesGeophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Elves are transient luminous events appearing above thunderclouds. They are produced by high peak current lightning events. They occasionally appear as doublets or in general as multiplets. We model elves doublets by setting the temporal and spatial variations of the return stroke current amplitude and we show that our modeling results are ...

Differences in Lightning—Storm Microphysical Relationships in Subtropical South America Versus the Continental U.S. and Their Impact on Model Lightning Parameterizations

open access: yesGeophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Satellite studies have shown that some of the deepest convection with high lightning flash rates occurs downstream of the Andes in subtropical South America (SSA). Using high resolution ground‐based observations in SSA, we explore the relationship between lightning and radar‐inferred storm microphysics.

Atmospheric Tides Imprint a Wavenumber‐4 Structure in Topside Ionospheric ELF Wave Intensity

open access: yesGeophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Atmospheric tides produce a well known pronounced longitudinal wavenumber‐4 (WN‐4) structure in the ionosphere, but their influence on electromagnetic‐wave propagation through the ionosphere remains poorly constrained. Here we use DEMETER satellite measurements to show that the extremely low frequency (ELF) electric field in the low‐latitude ...
