About the NAPLNThe North American Precision Lightning Networksm (NAPLNsm) is a geographic extension of the USPLN, and is comprised of the original U.S. sensors along with over 60 new sensors located throughout Canada, Mexico, the Caribbean, Central America and northern South America. The USPLN is a subset of the NAPLN coverage area. Additional sensors are planned to continue enhancing the density of the network. During the summer of 2009, the NAPLN Canadian coverage was enhanced through the addition of The Weather Network's lightning sensors.
While the original USPLN provides detections beyond the continental US borders, the additional sensors in the NAPLN cover these expanded areas:
- Canada – all provinces and portions of the territories
- Gulf of Mexico
- northern South America
- extended coastal regions
