Current Research

We have included a criteria for algorithmically identifying LASA waveforms which include both fast/intense stepped leader radiation and return stroke radiation. The algorithm first requires the identification of a negative CG, next requires a large negative excursion more than 200 $\mu$s before the return stroke, and finally requires a power ratio of greater than 100 of the 10 $\mu$s around the return stroke and the beginning of the record up to 6 $\mu$s before the return stroke. This crude criteria does find CGs with intense leader activity in the record. We are currently improving the leader recognition algorithm and implementing an algorithm to recognize non-NBE intracloud events. We will present the results in the accompanying poster.
