The Electric Field Change Meter (EFCM) is an airborne in situ electric meter. It is a two-channel (fast and slow) antenna used to measure the changes in the electric field produced by lightning. The fast channel has a sample rate of 10 MHz and is designed to detect the radiative component of the lightning discharge field. The slow channel has a sample rate of 1 MHz and is designed to observe the electrostatic field component. EFCM operates over the 1 Hz-100 kHz frequency range and has a detection limit of 25 km.
