Enabling High‐Fidelity Wave‐Particle Interaction Studies: A Novel Filtering for Isolating Whistlers From Spacecraft Noise

Geophysical Research Letters, Volume 53, Issue 5, 16 March 2026.
Abstract Resolving the mixture of natural plasma waves and persistent spacecraft interference is a fundamental challenge in space physics, as it obstructs the analysis of wave‐particle interactions and energy transport processes. Traditional signal decomposition methods often fail to adequately separate these components due to their time‐varying ...

Characterization and Localization of Chemical Explosions and Lightning Flashes by a Flotilla of Stratospheric Balloons

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 5, 16 March 2026.
Abstract On 3 August 2021, a flotilla of four Heliotrope solar hot air balloons was launched from central New Mexico (USA). The balloons, equipped with microbarometers, flew from sunrise to sunset at altitudes between 17 and 22 km. During the flight, eight chemical explosions ranging from 45 to 136 kg TNT equivalent and a thunderstorm occurred in the ...

Volcanic Ash Affected by Lightning During the Hunga 2022 Eruption

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 5, 16 March 2026.
Abstract The 15 January 2022 eruption of Hunga volcano (Kingdom of Tonga) produced the most lightning ever documented during an explosive eruption to date. This study estimates the mass of erupted tephra that may be structurally or electromagnetically affected by the lightning, based upon lightning peak current, channel length, and ash plume particle ...

Numerical Parameter‐Space Studies of Various Types of Thundercloud Gamma‐Ray Emissions

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 5, 16 March 2026.
Abstract Until recently, mainly two types of hard radiation were observed in thunderstorms: intensive, short‐lived terrestrial gamma‐ray flashes (TGFs) and weak, long‐lasting gamma‐ray glows (GRGs). The Airborne Lightning Observatory for Fly's Eye GLM Simulator and TGFs (ALOFT, GLM: Geostationary Lightning Mapper) flight campaign revealed additional ...

Discussions on a long gap discharge to an EHV transmission tower by a rocket triggered lightning experiment [PDF]

The triggered lightning experiments using a rocket have been carried out on a winter mountain in Japan since 1986. For the four years from 1986 to 1989, 39 rockets were launched and 19 of them triggered lightning strikes.

In‐Operando 4D‐STEM and STEM‐EBIC Imaging of Electric Fields and Charge Carrier Behavior in Biased Silicon p–n Junctions

Advanced Electronic Materials, Volume 12, Issue 5, 9 March 2026.
This work presents a study of how 4D‐STEM centre of mass measurements and STEM‐EBIC can be used to map the positions, directions, and strengths of electric fields in semiconductor devices. The contrast mechanisms of both techniques are tested and compared with simulations to build a robust analysis of an in situ device in the electron microscope ...

The Future of Hydrogen‐Powered Aviation: Technologies, Challenges, and a Strategic Roadmap for Sustainable Decarbonization

Advanced Energy and Sustainability Research, Volume 7, Issue 3, March 2026.
Hydrogen‐powered aviation offers a transformative pathway to zero‐emission flight by eliminating in‐flight CO2 emissions. Key considerations include propulsion systems (fuel cells and hydrogen combustion), cryogenic storage and insulation challenges, infrastructure and cost barriers, and supply‐chain constraints.

Economic Viability of Photovoltaic Systems Providing Frequency Containment Reserve

Advanced Energy and Sustainability Research, Volume 7, Issue 3, March 2026.
This article investigates the feasibility of photovoltaic (PV) systems providing frequency containment reserve (FCR) in the Netherlands. The economic analysis demonstrates that a PV plant can profitably participate in FCR without battery storage by maintaining an active power reserve.
