Broad band interferometric measurement of rocket triggered lightning in Japan

Geophysical Research Letters, 1997
A broad band interferometer to investigate the location of radio sources due to lightning flashes in two dimension has been manufactured and evaluated during the Rocket Triggered Lightning Experiment in Japan. Having high digitization rate, a broad band interferometer is not able to record the entire radiation process emitted by a lightning discharge ...

Discussions on a long gap discharge to an EHV transmission tower by a rocket triggered lightning experiment [PDF]

The triggered lightning experiments using a rocket have been carried out on a winter mountain in Japan since 1986. For the four years from 1986 to 1989, 39 rockets were launched and 19 of them triggered lightning strikes.

Lightning Return-Stroke Current Waveforms Aloft, from Measured Field Change, Current, and Channel Geometry [PDF]

, 2006
Three-dimensional reconstructions of six rocket-triggered lightning channels are derived from stereo photographs. These reconstructed channels are used to infer the behavior of the current in return strokes above the ground from current waveforms ...

Measurements of Unusual Precursors During the Very Initial Stage of Rocket‐Triggered Lightning

Geophysical Research Letters, Volume 52, Issue 17, 16 September 2025.
Abstract Eleven unusual precursors were observed in the initial stage of a classical triggered lightning event, which was performed on CMA‐FEBLS in the summer of 2024. The amplitudes of these unusual leaders exceeded 300 A, with pulse intervals from 30 to 200 ms, while their initiation height was only about 30 m.

Observation of an energetic radiation burst from mountain-top thunderclouds

, 2009
During thunderstorms on 2008 September 20, a simultaneous detection of gamma rays and electrons was made at a mountain observatory in Japan located 2770 m above sea level. Both emissions, lasting 90 seconds, were associated with thunderclouds rather than

Characterizing upward lightning with and without a terrestrial gamma-ray flash

, 2018
We compare two observations of gamma-rays before, during, and after lightning flashes initiated by upward leaders from a tower during low-altitude winter thunderstorms on the western coast of Honshu, Japan.
