An experimental VLF World-Wide Lightning Location (WWLL) network has been developed through collaborations with research institutions across the globe The aim of the WWLL is to provide global real-time locations of lightning discharges, with >50% CG flash detection efficiency and mean location accuracy of The detection efficiency of the WWLL is also considered In the selected region the WWLL detected ~13% of the total lightning, suggesting a ~26% CG detection efficiency and a ~10% IC detection efficiency Based on a comparison between all WWLL good lightning locations in February-April 2004, and the activity levels expected from satellite observations we estimate that the WWLL is currently detecting ~2% of the global total lightning, providing good locations for ~5% of global CG activity The existing WWLL network is capable of providing real-time positions of global thunderstorm locations in its current formread more

Long-range lightning geolocation using a VLF radio atmospheric waveform bank
TL;DR: In this paper, a new technique of long-range (≤6000 km) global lightning geolocation via sferic detection is presented, which catalogs the dominant variation in expected received waveforms in a set of waveform banks, which are then used to estimate the propagation distance and accurately determine the arrival time.
