recorded radio waves, monitoring frequencies below those detected by the NLDN sensors.
Fuelberg, 2010: Pre- and postupgrade distributions of NLDN reported cloud-to-ground lightning characteristics in the contiguous United States.
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.
Among the components of the NLDN are approximately 120 lightning sensors located across the country.
Once the information is stored in the control center's archives it is sent back to the satellite for transmission to NLDN users.
Originally, the NLDN was intended to benefit only the electric power industry, by enabling EPRI personnel to design lightning flash density maps to chart lightning strikes across the United States.
EUCLID is based on NLDN technology, combining both magnetic direction finding and TOA techniques as one, called Improved Accuracy through Combined Technology (IMPACT) sensors (Cummins et al.
During its lifetime, the flash produced at least nine positive CG strokes, four negative CG strokes, and four IC events, as reported by NLDN (Fig.
Before total lightning mapping, systems such as the NLDN (which locates primarily return strokes) would classify return strokes that were separated by a half a second or so in time, and tens of kilometers in distance, as separate flashes.
1%) were indicated by the NLDN to be of positive polarity.
The time-calibrated NLDN data are also available upon request and at no cost to universities for education and research (Unidata N.
