Monte Carlo model for analysis of thermal runaway electrons in streamer tips in transient luminous events and streamer zones of lightning leaders (2006, methodology): “This scaling is justified by the similarity properties of gas discharges [e.g., Liu and Pasko, 2004 , and references therein] and can be directly used for calculation of physical quantities at any other air density N of interest.”

Red sprite discharges in the atmosphere at high altitude: the molecular physics and the similarity with laboratory discharges (2007, methodology): “The ratios of various emissions arising from these states are very sensitive functions of the driving electric field and, if measured experimentally, can be directly compared with optical emission models such as those used in [44,62,88] (accounting for excitation and photon emission as well as quenc”
Review of recent results on streamer discharges and discussion of their relevance for sprites and lightning (2010, background): “But simulations [Liu and Pasko, 2004, 2006; Pasko, 2007; Luque et al., 2007, 2008b] show that the effect is minor as long as the electric field far ahead of the streamer is below the breakdown threshold.”
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, methodology): “…to happen when the radius of the streamer reaches several times the characteristic length scale of photoionization (cmin pO2) −1 ’ 0.2 cm at ground pressure in air [Liu and Pasko, 2004], where cmin and pO2 are the absorption coefficient and the partial pressure of molecular oxygen, respectively.”
