The Lightning Mapping Array (LMA) is a ground-based network of lightning detection sensors. An LMA network consists of very high frequency (VHF) antennas, GPS receivers, and processing systems that measure the location, time, and structure of total lightning. LMA has a horizontal spatial resolution of approximately 6-12 meters, a vertical resolution of approximately 20-30 meters, and a spatial extent of about 200 km from the network center. It has a typical sampling frequency of 10 µs with around 95% accuracy within 100 km of the network. LMA networks exist in several locations including Oklahoma, New Mexico, North Alabama, West Texas, Colorado, and Southern Ontario.
