Very High Frequency Lightning Observation

Sensor system

Broadband VHF circular flat-plate antennas operating in the 20–80 MHz band detect individual lightning stepped-leader pulses. GPS-synchronized sampling across 6 sites enables time-of-arrival 3D source mapping with sub-km accuracy over a ~20 km baseline.
