Since 2007, the USPLN has been extended with additional sensors outside of the continental United States to form the North American Precision Lightning Network (NAPLN). Therefore, the USPLN is now a subset of the NAPLN coverage area. The NAPLN includes over 60 new sensors throughout Canada, Mexico, the Caribbean, Central America and northern South America, increasing the geographic extent of coverage, with additional sensors planned. Most recently, the NAPLN Canadian coverage was enhanced with the addition of The Weather Network's lightning sensors. Distances between NAPLN sensors range from approximately 150 to 700 miles.
The Global Lightning Network is a separate network, comprised of over 120 sensors hosted at facilities throughout the world. The density and coverage of these sensors varies, as would be expected, and while the efficiency and accuracy metrics are highest in the Americas, Europe and Asia/Australia, we continue to expand the network with additional sensors. We welcome inquiries from interested potential site locations. A composite feed of the NAPLN and the GLN has been created to ensure the highest quality data set no matter where are customers are located.
Areas of 95% detection efficiency extend into most of the provinces of Canada for the NAPLN. Location accuracy is at least 250 meters (mean) throughout Canada, the Gulf, offshore Atlantic and into Mexico.
Sensor density, and hence metrics, are variable within the GLN. Detection efficiency ranges from 20% to 90% depending on geography. The key deployment areas (North/South America, Europe, Asia and Australia) have the highest metrics whereas oceanic regions are considerably less. With the addition of global sensors over the next year, overall performance will continue to increase.
