Fast Spectroscopy and Interferometry of a Lightning Flash
Abstract
Great progress has been made in high-speed lightning spectroscopy. It is advantageous to have additional instruments trained on the flash to provide context. Of particular interest would be to know currents in leaders simultaneous with having high-speed spectra thereof. On 7/26/2018, a daytime storm parked about 15 km NNW (250 degrees Azimuth) of the observing cupola at Langmuir Laboratory, over the plains of San Agustin. Data from a Phantom V2011, a broadband digital interferometer (INTF), a slow antenna system (LEFA) and a lightning mapping array (LMA) was correlated. In continuing these studies. we hope to be able to correlate spectra with temperature implied by channel currents derived from RF and slow-antenna techniques.
