Summary We have been developing an EM source location system using the VLF / LF bands based on broadband digital interferometry to monitor lightning activity in a wide area. Since EM waves in VLF / LF radiated by lightning discharges propagate a long distance, the VLF / LF interferometer locates lightning discharges a few hundred kilometers away from the VLF / LF interferometer. We conducted a lightning observation campaign using a prototype of a VLF / LF band digital interferometer and VHF band digital interferometers in Darwin, Australia. The VLF / LF radiation sources were located near those of the VHF source. We succeeded in locating the VLF / LF radiation sources associated with return strokes near the ground. © 2013 Wiley Periodicals, Inc.
