Characterizing lightning NOx production in the Ebro Valley with meteosat 12 LI and LMA observations [PDF]
Atmospheric Chemistry and PhysicsLightning is one of the main sources of NOx in the Earth's atmosphere, yet there is considerable variability in NOx production during thunderstorms. In this study, we combined optical lightning data from the Meteosat Third Generation (MTG) Lightning ...

3-Dimensional Lightning Observations Using a Time-of-Arrival Lightning Mapping System [PDF]
SAE Technical Paper Series, 2001 <div class="htmlview paragraph">A lightning mapping system has been developed that locates the sources of VHF radiation from lightning discharges in three spatial dimensions and time. The system consists of several VHF receivers distributed over an area of about 100 km diameter.

Advanced Intelligent Discovery, EarlyView.How much material loss is concealed beneath a layer of corrosion products? This proof‐of‐concept study demonstrates how concealed volume loss is inferred from the optical appearance and as‐exposed surface topography of AZ31 corrosion imprints. By predicting postcleaning depth maps, a multimodal U‐Net model estimates hidden volume loss without chromic ...

Ecoefficiency Analysis and Regression in Data Conversion for Spiking Neural Network Training
Advanced Intelligent Systems, EarlyView.The environmental footprint of spiking neural networks is quantified during dataset encoding and training for autonomous driving regression across three benchmarks. Temporal depth emerges as the dominant driver of energy consumption and CO2 emissions, while the accuracy–energy trade‐off proves dataset‐dependent. On conventional hardware, spiking models

IET Networks, EarlyView., 2022 Abstract 3D scanning is rapidly becoming a key maintenance tool. Aerospace was a pioneer in adopting 3D scanning technology because aircraft manufacture and maintenance require precision. Monitoring deterioration, removing components for maintenance, and verifying covert operations are not practical or helpful without technology.

Citizen Science Observation of a Gamma‐Ray Glow Associated With the Initiation of a Lightning Flash
Geophysical Research Letters, 2023 Gamma‐ray glows are observational evidence of relativistic electron acceleration due to the electric field in thunderclouds. However, it is yet to be understood whether such relativistic electrons contribute to the initiation of lightning discharges.
