About the NAPLN

Learn about the advantages of the NAPLN

The 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
• Mexico
• Caribbean
• Gulf of Mexico
• northern South America
• extended coastal regions

Lightning data for areas outside of North America is provided by the Global Lightning Network.
