Electromagnetic Measurement of and Location of Lightning
Electromagnetics, 1987ABSTRACT This paper summarizes some techniques developed for electromagnetic measurements of lightning electromagnetic fields at Langmuir Laboratory. These included measurement of transient electric and magnetic fields at the ground surface, use of these fields to estimate location of the lightning and properties of the source, and use of time of ...

VHF Technique for Locating Lightning
Radio Science, 1969The principles of a lightning location method using the VHF signals emitted by the discharge are outlined. Consideration of the source characteristics (notably signal strength and intervals between pulses; of the noise background; of the differences between the signals incident at spatially separated receivers; and of the electronic equipment now ...

Lightning Sferics for Lightning Location – Complex Analysis
2021<p>Lightning location networks commonly use the time stamps of the received radio waveforms from lightning flashes (sferics) at numerous stations to determine a single lightning flash location. In order to extract more information from the recorded lightning waveforms, a complex analysis of the received electromagnetic waves is ...

Performance of lightning locating systems in extracting lightning flash characteristics
Journal of Atmospheric and Solar-Terrestrial Physics, 2014Abstract A study was carried out to compare the negative cloud to ground lightning discharges recorded using Swedish lightning locating system against time correlated direct field measurements. Only the first 200 ms time window was investigated. A total of 167 flashes were recorded and time matched against the lightning locating system records.

Locations and Activities of Lightning Casualties
2018In developed regions of the globe, lightning protection is provided by the ready availability of lightning-safe structures and fully enclosed metal-topped vehicles during most daily activities of most people. In developing economies, in contrast, the lack of such lightning-safe structures and vehicles makes lightning safety very difficult to achieve ...

Waveform and location analyses of localised lightning locating system
2010 International Conference on High Voltage Engineering and Application, 2010Lightning mapping or locating systems are based on several working principles such as the Time of Arrival (ToA) and the Directional Finder (DF). The country wide lightning locating system (LLS) owned by TNB Malaysia is able to determine the coordinate of the cloud-to-ground lightning strike within 500m accuracy.

Lightning location with linet in Europe
2010 30th International Conference on Lightning Protection (ICLP), 2010Starting some 10 years ago the ‘Sferics Research’ group at the Physics Department of the University of Munich developed methods for lightning location based on the latest available technologies. Nowcast GmbH, an off-spring of this project, installed in 2006 the new system LINET in Europe and begun full operation.

Analytics of Lightning Data Collected by the Direct Measurement System and Lightning Location System
2018 IEEE PES Innovative Smart Grid Technologies Conference Europe (ISGT-Europe), 2018The paper presents the analytics of lightning data collected by monitoring system in real - time for the measurement of the direct lightning current (LAMS) and the lightning location system (LINET). The both systems and their operation mode are shortly described. A great number of collected data are analyzed, explained and compared.

U Hrvatskoj je krajem 2008.g. prvi put uspostavljen sustav za lociranje udara munja (eng. Lightning Location System – LLS) kao dio poznatog LINET sustava koji u Europi ima oko 100 senzora. Četiri senzora LINET sustava su instalirana na slijedećim lokacijama: Komolac kod Dubrovnika, Split, Melina kod Rijeke i Žerjavinec kod Zagreba.
