“…Using the VLF data for direction finding has a much greater accuracy since the temporal resolution (sampling freq. = 100 kHz) of the original lightning waveform is much better preserved [ Fullekrug et al , 1996]. On the other hand the waveform is not well resolved in the ELF data (sampling freq.…”

“…For the above reasons, the detection of radio waves from sprite‐producing lightning has been investigated as a means for globally geolocating transients associated with sprites [ Boccippio et al , 1995; Fullekrug et al , 1996; Cummer et al , 1998; Huang et al , 1999]. Some methods have used VLF antennas to determine the azimuth of the transients from a number of stations, with the resulting triangulation giving the location [ Reising et al , 1996].…”

The majority of sprites, the most common of transient luminous events (TLEs) in the upper atmosphere, are associated with a sub‐class of positive cloud‐to‐ground lightning flashes (+CGs) whose characteristics are slowly being revealed. These +CGs produce extremely low frequency (ELF) and very low frequency (VLF) radiation detectable at great distances from the parent thunderstorm. During the STEPS field program in the United States, ELF/VLF transients associated with sprites were detected in the Negev Desert, Israel, some 11,000 km away. Within a two‐hour period on 4 July 2000, all of the sprites detected optically in the United States produced detectable ELF/VLF transients in Israel. All of these transients were of positive polarity (representing positive lightning). Using the VLF data to obtain the azimuth of the transients, and the ELF data to calculate the distance between the source and receiver, we remotely determined the position of the sprite‐forming lightning with an average locational error of 184 km (error of 1.6%).

“…The +CG precondition for sprites led us to investigate the ULF response to +CG lightning as such, irrespective of sprite association. In this direction there exist previous research studies under the headline of transient Schumann resonance or “Q‐bursts” [e.g., see Füllekrug and Fraser‐Smith , 1996; Füllekrug et al , 1996; Füllekrug and Reising , 1998]. The term Q‐burst was created as a label for large Schumann resonance bursts (transients) which exceed the usual magnetic background noise to such an extent that they can be treated as single, individual magnetic response signatures to exceptionally intense lightning discharges.…”

Is there a unique signature in the ULF response to sprite‐associated lightning flashes?

[1] Using observations made by the Finnish chain of pulsation magnetometers, we select typical properties of the ULF response to sprite-associated lightning events taken from the EuroSprite 2003 summer campaign. We concentrate on frequencies below the Schumann resonance and compare the obtained results with properties obtained from positive cloud-to-ground lightning discharges which are not associated with sprites. The latter we take from listings of the Météorage Lightning Detection Network, which correlate with strong impulsive events seen in the Finnish chain. The evidence shows no unique and identifiable ULF signature relating to the sprite causative discharges.

In addition, by comparing the azimuth angle to lightning strokes obtained from ELF observations by the method described in section 3 and the azimuth calculated from the strokes' coordinates, some physical properties of the Earth-ionosphere waveguide can be investigated [Füllekrug et al, 1996;Füllekrug and Sukhorukov, 1999].…”

Cloud-to-ground lightning dipole moment from simultaneous observations by ELF receiver and combined direction finding and time-of-arrival lightning detection system

[1] We present a new method of automatic detection of ELF impulses related to cloud-to-ground lightning at distances 1-2 Mm from a broadband ELF receiver and also we present a new numerical automated technique for calculating the lightning dipole moment. We have performed the detection for two known data sets of lightning flashes detected by the French lightning detection network Meteorage in southwest Europe over two 48 h periods 28-29 July and 6-7 September 2005. The number of flashes identified in the ELF data compared to the number of flashes detected by Meteorage reach 10-25% when little local activity close to the ELF station is present. The local thunderstorm activity worsens the detection of lightning from larger distances and the efficiency of identification of ELF impulses as lightning can decrease to a few percent. By combining the information on the location of the lightning flashes from Meteorage with the ELF data, lightning dipole moments can be calculated. Our results suggest the dipole moment is linearly correlated with the lightning peak current (p ' 7.5 I max ) but the dispersion of the dipole moment for a given peak current is significant. One of the reasons of such dispersion is the contribution of the lightning continuing current to the ELF signal.Citation: Nieckarz, Z., A. Kulak, S. Zieba, and A.
