Improvements to the BOLT lightning location system

The Broadband Observational network for Lightning and Thunderstorms (BOLT) is a network of low frequency electric field antennas which is capable of mapping lightning flashes in 3D. We are currently investigating improvements to both the hardware design of the BOLT antennas, and to the algorithm used to determine each lightning source location. The antenna revision increases the sensitivity of the antenna to frequencies most beneficial to lightning location. The processing algorithm improvements have increased the number of lightning sources located, and produce 3D maps of sufficient quality for charge analysis.
