Abstract

We examine electric field waveforms produced by 69 negative return strokes in 13 flashes triggered using the rocket-and-wire technique at Camp Blanding, Florida, in 2012. The waveforms were recorded at the Lightning Observatory in Gainesville, at a distance of 45 km from the lightning channel. This is the first detailed characterization of far (essentially radiation) electric field waveforms produced by rocket-triggered lightning. The results will be used in examining similarities and dissimilarities between natural and rocket-triggered lightning processes.
