Cloud-to-Ground lightning location using TOGA of sferics

Lightning measurements have been extensively utilised by power companies, metereological offices as well as by the scientific community in general. As opposed to the Intra-Cloud (IC) discharge, the Cloud – to – Ground (CG) lightning stroke $ a major safety hazard. In CG lightning stoke, the stepped leader decending from the base of a thundercloud triggers the first return stroke. This stroke is responsible for most of the charge transfer within few tens of microseconds causing a current of tens of kA. In this report, we present a novel CG stroke location accuracy of ≈2km.
