Comprehensive Lightning Observation Using VHF Interferometer and LHAASO

The relationship between lightning and high-energy particles has been a hot topic in our field recently. We conducted a lightning observation campaign to investigate the characteristics of high-energy particles before and after the inception of natural lightning. The campaign utilized the Large High Altitude Air Shower Observatory (LHAASO), which is equipped with over 4,000 electromagnetic particle detectors covering a 1 km² area, capable of detecting high-energy particles with nanosecond precision. In conjunction with LHAASO, we deployed two VHF interferometers to image lightning channels with equally high resolution. Since the campaign's inception, we have captured many lightning flashes alongside synchronous high-energy particle detections. This paper presents preliminary results during the last two years, including observations of Terrestrial Gamma-ray Flashes (TGFs) and Thunderstorm Ground Enhancements (TGEs), offering new insights into the relationship between cosmic rays and lightning initiation.
