Journal ArticleDOI
VLF lightning location by time of group arrival (TOGA) at multiple sites
TL;DR: In this paper, the authors used the time of group arrival (TOGA) of the VLF (3-30 kHz ) radiation from a lightning stroke to locate lightning.
Journal ArticleDOI
Detection efficiency of the VLF World-Wide Lightning Location Network (WWLLN): initial case study
Craig J. Rodger,Simon Werner,James B. Brundell,Erin H. Lay,Neil R. Thomson,Robert H. Holzworth,Richard L. Dowden +6 more
TL;DR: In this paper, the authors examined the detection efficiency of the WWLLN by comparing the locations from this network with lightning location data purchased from a commercial lightning location network operating in New Zealand.
Journal ArticleDOI
Performance Assessment of the World Wide Lightning Location Network (WWLLN), Using the Los Alamos Sferic Array (LASA) as Ground Truth
TL;DR: The World Wide Lighting Location Network (WWLLN) as discussed by the authors locates lightning globally, using sparsely distributed very low frequency (VLF) detection stations and is able to detect intracloud and cloud-to-ground discharges with comparable efficiency as long as the current is comparable.
Journal ArticleDOI
WWLL global lightning detection system: Regional validation study in Brazil
Erin H. Lay,Robert H. Holzworth,Craig J. Rodger,Jeremy N. Thomas,Osmar Pinto,Richard L. Dowden +5 more
TL;DR: In this article, the authors analyzed the performance of the World Wide Lightning Location Network (WWLL) with respect to time, location, and peak current of lightning strokes in Brazil and found that the detected strokes have a location accuracy of 20.25 ± 13.5 km and a temporal accuracy of 0.06 ± 0.2 ms.
Journal ArticleDOI
Location accuracy of VLF World-Wide Lightning Location (WWLL) network: Post-algorithm upgrade
TL;DR: An experimental VLF World Wide Lightning Location (WWLL) network has been developed through collaborations with research institutions across the globe as discussed by the authors to provide global real-time locations of lightning discharges, with >50% flash detection efficiency and mean location accuracy.
