LOFAR Lightning Imaging: Mapping Lightning With Nanosecond Precision [PDF]
Journal of Geophysical Research D: Atmospheres, 2018 AbstractLightning 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, even for lightning flashes that are ...

Characteristics of Lightning within Electrified Snowfall Events using Lightning Mapping Arrays. [PDF]
J Geophys Res Atmos, 2018 AbstractThis study examined 34 lightning flashes within four separate thundersnow events derived from lightning mapping arrays (LMAs) in northern Alabama, central Oklahoma, and Washington DC. The goals were to characterize the in‐cloud component of each lightning flash, as well as the correspondence between the LMA observations and lightning data taken
