Three-dimensional finite difference time domain modeling of the Schumann resonance parameters on Titan, Venus, and Mars
Yang, Heng; Pasko, Victor P.; Yair, Yoav
The conducting ionosphere and conducting surface of Titan, Venus, and Mars form a concentric resonator, which would support the possibility of the existence of global electromagnetic resonances. On Earth, such resonances are commonly referred to as Schumann resonances and are excited by lightning discharges. The detection of such resonances on oth…
Extreme solar EUV flares and ICMEs and resultant extreme ionospheric effects: Comparison of the Halloween 2003 and the Bastille Day events

Extreme solar flares can cause extreme ionospheric effects. The 28 October 2003 flare caused a ~25 total electron content units (TECU = 1016 el/m2 column density), or a ~30%, increase in the local noon equatorial ionospheric column density. The rise in the TEC enhancement occurred in ~5 min. This TEC increase was ~5 times the…
