The Electrical Measurement by Sounding Balloons and a Flexibility Study on the Artificially Triggered TLEs
Abstract
The atmospheric electric field plays an important role in driving the global electric circuit, as well as the theoretical models of the transient luminous events (TLEs). The measurement of the electric field in the upper atmosphere, especially above cloud top to the bottom of the ionosphere is very challenging but essential. A lightweight, double-Langmuir type probe of the electric field meter is greatly improved for the balloon-borne measurement. Instead of scientific balloons, the meteorological balloons are used to send this electric field meter to up to 30km height and measure the vertical profile of the atmospheric electric field, and the vertical charge density can also be derived simultaneously. In this presentation, the result of a flight is demonstrated. In addition to the measurement of the electric filed, the artificial TLEs triggered from meteorological balloon is also considered. A simple electrodynamic model similar to Krehbiel et al. [2008] is adapted to explore the possibility and conditions to induce the electric field breakdown and produce artificial TLEs by cooper wires in the upper atmosphere. The preliminary results are also reported.
