An Electric Field Mill (EFM) is an in situ airborne and ground-based electric sensor designed and built at NASA Marshall Space Flight Center (MSFC). It measures the full vector components of the atmospheric electric field and provides details about the electrical structure within and around a storm. EFMs can detect both intracloud and cloud-to-ground lightning and can operate during large thunderstorm fields (thousands of volts/meter). An EFM has a typical time response of about 10 Hz.
