With this reference and the notes of observers at other sites, researchers can triangulate sprites' exact locations and link individual sprites to discharges measured by the NLDN.
Because the charge in the top half of a storm cloud is positive, the lightning that favors sprites shows up as a positive current in NLDN data.
The technology of the NLDN is a key factor in the accuracy and reliability of the data in STRIKEnet reports.
American Airlines (Dallas) has incorporated the NLDN in its operations.
At Baltimore Gas & Electric Co., the utility has been able to restore power lost in the wake of electrical storms hours earlier than before by using NLDN data as a prior warning of thunderstorm activity.
Tucson, Ariz.-based Global Atmospherics, which operates the National Lightning Detection Network (NLDN), a catalog of cloud-to-ground lightning strikes in the U.S.
As a result, the company's NLDN information dissemination system, called StrikeFax, is still distributed via its namesake.
The study was based on the National Lightning Detection Network (NLDN; Cummins et al.
Most lightning monitoring groups around the world utilize very low-frequency (VLF)/ low-frequency (LF) lightning detection networks such as the National Lightning Detection Network (NLDN), a system that provides accurate data on the time, location, amplitude, and polarity of the individual return strokes in CG flashes, and also detects some IC strokes (Cummins et al.
Each video sequence was accurately calibrated in time by comparing the time intervals between lightning flash occurrences, particularly cloud-to-ground (CG) flashes, to a reference dataset available in the remotely sensed National Lightning Detection Network (NLDN) flash archive (Cummins and Murphy 2009).
