Summary
Abstract:
The network is comprised of the U.S. National Lightning Detection Network (NLDN) and the Canadian Lightning Detection Network (CLDN), the latter commissioned for operations in February 1999. These two networks comprise an integrated North American Lightning Detection Network (NALDN) consisting of 187 sensors (Cummins et al., 1999). The sensors 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 Gulf of
Mexico, the Atlantic, and the Pacific Oceans. A combination of time of arrival
and direction finding technology is used to locate each flash. Depending on the
location within the network, GAI claims a location accuracy of 500 meters, with
a detection probability between 80-90 percent, varying by region. These data
are ingested in real-time and stored in a raw data file. Distribution of this
data set is restricted to Earth Observing System (EOS) and TRMM affiliated
investigators.
