Electric field measurements in a NLC/PMSE region during the MASS/ECOMA campaign
We present results of electric field measurements made during the MASS rocket campaign in Andøya, Norway into noctilucent clouds (NLC) and polar mesospheric summer echoes (PMSE) on 3 August 2007. The instrument used high input-impedance preamps to measure vertical and horizontal electric...

| description | We present results of electric field measurements made during the MASS
rocket campaign in Andøya, Norway into noctilucent clouds (NLC) and
polar mesospheric summer echoes (PMSE) on 3 August 2007. The
instrument used high input-impedance preamps to measure vertical and
horizontal electric fields. No large-amplitude geophysical electric
fields were detected in the cloud layers, but significant levels of
electric field fluctuations were measured. Within the cloud layer,
the probe potentials relative to the rocket skin were driven negative
by incident heavy charged aerosols. The amplitude of spikes caused by
probe shadowing were also larger in the NLC/PMSE region. We describe a
method for calculating positive ion conductivities using these
shadowing spike amplitudes and the density of heavy charged aerosols. |
