Coordinated TLE Campaign using ISUAL and NCKU ULF, ELF/VLF Stations
Abstract
Imager of Sprites and Upper Atmospheric Lightning (ISUAL in short) payload on the FORMOSAT-2 satellite and two ULF and ELF/VLF radio band recording stations in Taiwan are used to further study the characteristics and the correlation between transient luminous events (TLEs) and their associated sferics. From June 2009 to June 2012, 7,276 elves, 733 sprites, 415 halos, 1,671 blue jets, and 22 gigantic jets (GJs) were recorded by ISUAL. More than 50% of these TLEs were found to have corresponding sferics. In all, ~0.5% of sprite-inducing lightning and 80% of halo-inducing lightning are inferred to be generated by negative discharges. However, in sharp contrast to previous studies, this work found that more than 90% of elves are induced by negative lightning.
