ELF/VLF monitoring of lightning activity in Taiwan*

Currently, there are two long-range lightning monitoring systems operating in Taiwan; one is a VLF/ELF electric field detection system and the other one is an ELF (SR) magnetic field system. The electric field system detect the electric sferics emitted by lightning in the 1 Hz to 22 kHz range. The magnetic system operates in the frequency range of 1 Hz to 100 Hz. In the 2003 Taiwan Sprites campaign, these two systems worked in parallel with a set of ICCD cameras to study oceanic sprites occurring in the South China Sea. From the ELF and optical data, the correlation between optical luminosity of sprites and amplitudes of their associate ELF emission was found. We will also discuss the possible correlation between the morphology of sprites and the waveform of their associate ELF signals. * This work was partially supported by 92-NSPO(B)-ISUAL-FA09-01 and NSC 92-2111-M-006-002
