Instrumental Artefacts Can Reverse Apparent Lightning–Climate Trends

open access: yesGeophysical Research Letters
Lightning is an Essential Climate Variable, yet long‐term detection records may be compromised by changes in detection technology. Using more than three decades of Austrian lightning observations (1992–2024), we show that instrumental artefacts can ...

Application of 3D scanning technology in Royal Malaysian Air Force Industrial Revolution 4.0‐based aircraft maintenance

open access: yesIET 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.

Channel branching and zigzagging in negative cloud-to-ground lightning [PDF]

open access: yesScientific Reports, 2017
AbstractA fundamental question in lightning flash concerns why the discharge channel propagates in a zig-zag manner and produces extensive branches. Here we report the optical observation of two negative cloud-to-ground lightning discharges with very high temporal resolution of 180,000 frames per second, which shows in detail the dependence of channel ...

Characterization of negative cloud-to-ground lightning in Florida [PDF]

open access: yesJournal of Atmospheric and Solar-Terrestrial Physics, 2015
Abstract We examined characteristics of negative cloud-to-ground lightning flashes using their electric field waveforms acquired at the Lightning Observatory in Gainesville (LOG), Florida in the summers of 2013 and 2014. Flash multiplicity, interstroke interval, flash duration, and first to subsequent stroke field peak ratio are determined for 478 ...
