Determination of Detection Efficiency of Lightning Detection Systems using Bayesian Analysis

In the context of a Bayesian analysis, this leads to a relative probability of detection for the two systems. Hence the relative information content of one system relative to another can be determined. Further application of probability theory can yield an upper limit on the absolute detection efficiency of each system.

We present results comparing the Earth Networks Total Lightning Network (ENTLN) and the Lightning Imaging Sensor (LIS). We do not compare flashes; since lightning processes that result in detectable light from space also produce detectable electric field changes, the base unit of each data set are directly comparable. By using ENLTN pulses and LIS groups, we minimize the fundamental bias that exists in flash sorting algorithms.
