Abstract
The data acquired under phase 2 of the subject contract were analyzed to investigate whether the electric field strength and/or abrupt changes in the electric field could be used as device- independent parameters for a lightning warning safety specification. Although the data analyzed were device specific, the following conclusions were reached: (1) a safety specification based upon the electric field strength at a single point is ineffective; the specification must also include an area of coverage that implies the use of multiple sensors. (2) A safety specification based upon flash rate or relative magnitude of received atmospherics is ineffective owing to the large variability in the measurement parameter. (3) A safety specification based upon an indication of atmospheric electrical activity within a predetermined radius of the site is viable and does not attempt to solve the difficult problem of estimating the location of the activity.
