Abstract

Fully calibrated wide-band (lHz<f<lkHz) three-component ELF measurement system has been installed as a permanent station in Moshiri, Hokkaido Japan in December 1996. We have been observing continuous background signals including Schumann resonances and ELF transient events. Preliminary data a~alysis shows the clear diurnal and seasonal patterns of global thunderstorm activities deduced from Schumann resonance amplitudes, and the global mapping of lightning locations are produced by using ELF events. Further the ELF events in association with mesospheric optical events are discussed.
