A real-time, multi-sensor local-area lightning detection network system. The system uses waveform indicative of electrostatic field changes with respect to time is generated at each of N locations due to a cloud-to-ground lightning strike occurring in the vicinity of the N locations. Each waveform is integrated to generate a corresponding electric field associated with a corresponding one of the locations. A mathematical relationship is used to determine a ground surface location of the lightning strike, height of the lightning strike, and charge per unit length of the lightning strike using each electric field generated during integration of the waveforms.
