A thunderstorm near Yakutsk on July 1, 2020, according to measurements by three instrumental systems

Abstract

In 2009, two lightning location systems were installed in the center of the city of Yakutsk: the sferic sensor of the World wide lightning location network (WWLLN) and single-point lightning direction finder Stormtracker (Boltek Co.). The third system was an electric field mill detector (fluxmeter) EZ NMLS 411124000 (NIRFI UNN). In this paper, we present a preliminary comparative analysis of measurements by three systems of a nighttime thunderstorm on July 1, 2020, in the vicinity of the city at 14–16 UT and a video sequence in a half-hour period around 15 UT.
