Three-dimensional time domain model of lightning including corona effects [PDF]

open access: yes
A new 3-D lightning model that incorporates the effect of corona is described for the first time. The new model is based on a Thin Wire Time Domain Lightning (TWTDL) Code developed previously.

Fail‐Controlled Classifiers: A Swiss‐Army Knife Toward Trustworthy Systems

open access: yesSoftware: Practice and Experience, Volume 56, Issue 3, Page 239-259, March 2026.
ABSTRACT Background Modern critical systems often require to take decisions and classify data and scenarios autonomously without having detrimental effects on people, infrastructures or the environment, ensuring desired dependability attributes. Researchers typically strive to craft classifiers with perfect accuracy, which should be always correct and ...

Characteristics of Negative Cloud‐To‐Ground Lightning Flashes Associated With Their Peak Currents of First Return Strokes

open access: yesEarth and Space Science, Volume 13, Issue 3, March 2026.
Abstract This study investigates the characteristics of negative cloud‐to‐ground (CG) lightning flashes across varying peak current (PCs) ranges by combining 3D location data from 2,597 negative CG flashes with radar observations. The flashes were classified into five PC bins: −25 kA < PC < 0 kA, −50 kA < PC < −25 kA, −75 kA < PC ≤ −50 kA, −100 kA < PC

Method and apparatus for determining return stroke polarity of distant lightning [PDF]

open access: yes
A method is described for determining the return stroke polarity of distant lightning for distances beyond 600 km by detecting the electric field associated with a return stroke of distant lightning, and processing the electric field signal to determine ...

Ionospheric Characterization Using VLF Whistlers

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract Broadband very low frequency (VLF, 3–30 kHz) energy emitted from lightning travels long distances in subionospheric propagation modes. Some of this energy couples into the ionosphere and travels to satellite altitudes along a predominantly field‐aligned path in what is known as a “whistler” propagation mode. Along this path, these VLF signals (
