National Lightning Detection Network (NLDN)

National Lightning Detection Network (NLDN) Data Sets
The U.S. National Lightning Detection Network (NLDN) is a commercial lightning detection network operated by Vaisala.  A network of antennae are connected to a central processor that records the time, polarity, signal strength, and number of strokes of each cloud-to-ground lightning flash detected over the United States.

These data are restricted to collaborators that have a working relationship with the NASA Marshall Space Flight Center (MSFC) Lightning Group.
