Which necessitates the use of a very tall structure (e.g. the CN Tower), a moderately tall structure erected on high ground, or the utilization of rocket- or laser- triggered lightning.
This paper emphasizes the current measurement techniques and instrumentation, and reports on statistics of the current wavefront parameters of lightning current waveforms recorded in 1999. Based on these results, recommendations will be provided for the proper measurement of lightning currents, especially those which are captured at elevated objects.
