The Electric Field Change Meter (EFCM) is an airborne in situ electric meter. It uses a two-channel (fast and slow) antenna system to measure electric field changes caused by lightning. The fast channel samples at 10 MHz and detects the radiative component of lightning discharges. The slow channel samples at 1 MHz and observes the electrostatic field component. The EFCM operates across a frequency range of 1 Hz to 100 kHz and has a detection radius of 25 km.
