Proposal Title: High-resolution observation of the electric eld and neutral wind inside the night-
time traveling ionospheric disturbances
ABSTRACT:
We propose to measure both the electric eld and meridional neutral wind with the high temporal resolution
provided by the dual radar beams in order to clarify the physical mechanism of nighttime traveling ionospheric
disturbances (TIDs). The signicant question regarding nighttime TIDs is whether TIDs are a passive response to
the neutral wind, as described by the classical theory, or are electrodynamism nature, as indicated by the Arecibo
radar in 1993 [Miller et al., 1997]. To solve this problem, the electric eld and neutral wind will be observed by the
Arecibo radar and the Fabry-Perot interferometer, and the two-dimensional structures of TIDs will be detected by
an all-sky camera. TIDs have a few hundred kilometer scale size and travel to the southwest with a velocity of
100m/s. Therefore, high temporal resolution observations are crucial in determining the relationship between the
electric eld, the neutral wind and phase of the TIDs.
