LOFAR Lightning Imaging: Mapping Lightning With Nanosecond Precision [PDF]
Journal of Geophysical Research D: Atmospheres, 2018 Abstract Lightning mapping technology has proven instrumental in understanding lightning. In this work we present a pipeline that can use lightning observed by the LOw‐Frequency ARray (LOFAR) radio telescope to construct a 3‐D map of the flash. We show that LOFAR has unparalleled precision, on the order of meters,

VHF Lightning Mapping Observations of a Triggered Lightning Flash [PDF]
Geophysical Research Letters, 2012 On 3 August 2010 an extensive lightning flash was triggered over Langmuir Laboratory in New Mexico. The upward positive leader propagated into the storm's midlevel negative charge region, extending over a horizontal area of 13 × 13 km and 7.5 km altitude. The storm had a normal‐polarity tripolar charge structure with upper positive
