Complex AC and DC electric fields are known to be associated with polar mesospheric summer echo (PMSE) density irregularities and noctilucent cloud (NLC) layers. A two-channel prototype electric field instrument based on the double probe technique was developed to measure electric fields on-board a MIDAS (Middle atmosphere Investigation of Dynamics And Structure) sounding rocket. The instrument measures electric field variations up to 4 kHz, with 8 bit resolution. The payload was launched on 2 July 2002 from Andøya Rocket Range (69°N, 16°E) in Norway, in the presence of a PMSE radar backscatter layer located between 82 and 85 km height. The AC measurements in the PMSE region are characterized by spiky waveforms with amplitudes of a few mV/m, and the AC variations were also present in the height region 81-82 km, i.e. below the PMSE and NLC layers.
