Abstract
Transient luminous event coordinated observations using FORMOSAT-2 satellite and Taiwan sprites campaign
Highlights
By analyzing the images of columniform sprites recorded in a single site observation, Vadislavsky et al (2009) found that the sprite columns were arranged in highly eccentric elliptical forms or in straight rows, suggesting that the columniform sprite elements are organized in spaced intervals on the circumference of a circle centered directly above, or with a little offset to, the parent lightning
We report on two events recorded by the Imager of Sprites and Upper Atmospheric Lightning (ISUAL) and Taiwan transient luminous event (TLE) ground campaign coordinated observations
Spherical trigonometry and systematic procedures were employed for the triangulation of TLEs
Summary
Since Franz et al (1990) recorded the first sprite with a low light camera in 1989, numerous observations have been carried out from the ground (Fukunishi et al 1996; Stenbaek-Nielsen et al 2000; Pasko et al 2002; Su et al 2002, 2003; Hsu et al 2003; Van der Velde et al 2007; Chou et al 2010; Huang et al 2012; Yang et al 2013, 2015), airplane (Sentman et al 1995; Wescott et al 1995), and space (Boeck et al 1998; Kuo et al 2005; Chen et al 2008; Chang et al 2010; Chou et al 2010; Lee et al 2010, 2012; Jehl et al 2013). By analyzing the images of columniform sprites recorded in a single site observation, Vadislavsky et al (2009) found that the sprite columns were arranged in highly eccentric elliptical forms or in straight rows, suggesting that the columniform sprite elements are organized in spaced intervals on the circumference of a circle centered directly above, or with a little offset to, the parent lightning They used a quasi-electrostatic (QE) field model with a charge above the conducting surface to demonstrate that the observed diameter and view angle of the columnar arrangement was close to the conventional breakdown field line contour at the same altitude. The ISUAL TLE geolocation accuracy and detection efficiency will be discussed
