Abstract. 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 form.

An Overview of Lightning Locating Systems: History, Techniques, and Data Uses, With an In-Depth Look at the U.S. NLDN (2009, methodology): “The World Wide Lightning Location Network (WWLLN – [99]-[102]) utilizes a time-of-grouparrival (TOGA) method to locate lightning strikes.”
Highlights of a New Ground-Based, Hourly Global Lightning Climatology (2012, background): “WWLLN preferentially detects strong cloud-to-ground strokes, and it rarely detects and locates multiple strokes within a single flash because the dispersed waveforms overlap or because there is a large difference in total radiated energy (Rodger et al. 2004, 2005; Jacobson et al. 2006).”
Long‐range lightning geolocation using a VLF radio atmospheric waveform bank (2010, background): “WWLLN has been periodically upgraded since its first inception in 2002 [Rodger et al., 2004, 2005, 2009] and 2 of 19 included 40 receivers as of July 2010 (http://webflash.ess. washington.edu/).”
