Instrument

EFCM
Electric Field Change Meter

The Electric Field Change Meter is an instrument that detects changes in the electric field that occur after lightning flashes. It has been used as both a field instrument and an airborne instrument. It has a high temporal resolution, making it useful for taking measurements before, during, and after lightning flashes.
