The Gerdien Probe is an in situ airborne conductivity device. It measures atmospheric electrical conductivity by recording the time it takes for a sample of air to discharge after being exposed to a capacitor. The Gerdien probe can detect both positive and negative ions. It can be mounted on aircraft, uncrewed aerial systems (UAS), and rockets.
