The participating lightning location systems (LLSs) were Sferics Timing and Ranging Network (STARNET), Rede Integrada Nacional de Deteccao de Descargas Atmosfericas (RINDAT), World Wide Lightning Location Network (WWLLN), Arrival Time Difference Network (ATDnet
), Vaisala Global Lightning Dataset 360 (GLD360) and Total Lightning Sensor (TLS200), Sistema Brasileiro de Deteccao de Descargas Atmosfericas (BrasilDAT), Lightning Network (LINET), and Lightning Mapping Array (LMA).
UK Met Office's long-range lightning location network (ATDnet
) had measured lightning generated during the volcanic activity.
