Lightning mapping observation of a terrestrial gamma‐ray flash (2010, background): “, 1992], and their connection with lightning discharges is documented by detecting low frequency radio emissions [Inan et al., 1996, 2006; Cummer et al., 2005; Stanley et al., 2006; Cohen et al., 2010; Shao et al., 2010].”
Energy and fluxes of thermal runaway electrons produced by exponential growth of streamers during the stepping of lightning leaders and in transient luminous events (2011, background): “[3] Numerous experimental and theoretical works have strongly confined the conditions in which a TGF can occur [e.g.,Cummer et al., 2005;Dwyer and Smith, 2005; Stanley et al., 1Department of Electrical Engineering, Communications and Space Sciences Laboratory, Pennsylvania State University,…”
A closer examination of terrestrial gamma‐ray flash‐related lightning processes (2010, methodology): “For 26 RHESSI TGFs, Cummer et al. [2005] reported that 13 were linked to lightning discharges, as measured by their ELF/VLF sensors, and that all 13 were found to be +CG‐like positive‐polarity discharges.”
High-Energy Atmospheric Physics: Terrestrial Gamma-Ray Flashes and Related Phenomena (2012, background): “The analysis of 30 kHz and lower frequency radio emissions during 26 TGFs (Cummer et al. 2005) showed that 13 of them occurred within several milliseconds of detectable positive polarity (those that transfer positive charge downward) lightning processes.”
Source mechanisms of terrestrial gamma‐ray flashes (2008, methodology): “[4] In addition, using sferic observations Cummer et al. [2005] found that 13 of the RHESSI TGFs were associated with positive polarity lightning discharges, but the charge moment changes of these events were too small to be associated with sprites and were about two orders of magnitude smaller th”
A comparison between Monte Carlo simulations of runaway breakdown and terrestrial gamma‐ray flash observations (2005, methodology): “Using sferics observations Cummer et al. [2005] found that 13 of the RHESSI TGFs were associated with positive polarity Figure 2. TGF counts spectrum as measured by RHESSI and the X-ray emission spectra, corrected for the instrumental response, as calculated by the Monte Carlo simulation of runawa”
A link between terrestrial gamma‐ray flashes and intracloud lightning discharges (2005, methodology): “The expected arrival time of electromagnetic radiation at RHESSI was 5.1 ms after the actual time, which is more than 2 ms outside of the range estimated by [Cummer et al., 2005].”
First results on terrestrial gamma ray flashes from the Fermi Gamma‐ray Burst Monitor (2010, background): “A larger number of associations have been found for RHESSI TGFs, with the results having a dispersion of several milliseconds, typically with a mean offset of TGFs preceding sferics [Cummer et al., 2005; Stanley et al., 2006; Inan et al., 2006; Lay, 2008; Cohen et al., 2010].”
