Basic lightning flash properties derived from lightning mapping array data

, 2016
The size and duration of lightning flashes are examined. Data from the Ebro Valley Laboratory Lightning Mapping Array is used as reference. Additional data from the VLF/LF LINET network is included. In the analysis, each flash is simplified by a confidence ellipse fitting most of the detected sources.

Surface‐Driven Protocell Formation in Geologically Relevant Early Earth Environment

ChemSystemsChem, Volume 8, Issue 2, March 2026.
Illustration of a prebiotic early‐Earth environment showing cell‐like protocells (blue spheres) and other complex organic molecules (pink and green spheres) distributed across terrestrial surfaces and within subsurface niches. Volcanic landscapes and mineral‐rich substrates provide diverse geochemical settings for the assembly and evolution of ...

On the Beam Characteristics of X‐Ray Bursts Observed in Rocket‐Triggered Lightning

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.
Abstract Employing the multi‐station Thunderstorm Energetic Radiation Observation System, we detected X‐ray bursts during two rocket‐triggered lightning events in 2024. By innovatively integrating optical imaging with three‐dimensional lightning channel reconstruction based on Distributed Acoustic Sensing (DAS), we analyzed the X‐ray emission ...

First results from the TUS orbital detector in the extensive air shower mode

, 2017
TUS (Tracking Ultraviolet Set-up), the first orbital detector of extreme energy cosmic rays (EECRs), those with energies above 50 EeV, was launched into orbit on April 28, 2016, as a part of the Lomonosov satellite scientific payload. The main aim of the

The rarity of terrestrial gamma-ray flashes [PDF]

, 2011
We report on the first search for Terrestrial Gamma-ray Flashes (TGFs) from altitudes where they are thought to be produced. The Airborne Detector for Energetic Lightning Emissions (ADELE), an array of gamma-ray detectors, was flown near the tops of ...

A low‐frequency near‐field interferometric‐TOA 3‐D Lightning Mapping Array

Geophysical Research Letters, 2014
AbstractWe report on the development of an easily deployable LF near‐field interferometric‐time of arrival (TOA) 3‐D Lightning Mapping Array applied to imaging of entire lightning flashes. An interferometric cross‐correlation technique is applied in our system to compute windowed two‐sensor time differences with submicrosecond time resolution before ...

Ice‐Nucleating Particle and Cloud Ice Crystal Concentrations Associated With Developing Summertime Deep Convective Clouds in South‐Western USA

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 3, 16 February 2026.
Abstract Ice‐nucleating particles (INPs), essential for initiating primary ice production in many mixed‐phase clouds, have only rarely been measured in air directly relevant for deep convective clouds. In July–August 2022 we used an aircraft to sample aerosol near developing deep convective clouds over Magdalena Mountain, New Mexico, USA.
