Detrended average plasma densities from the Planar Langmuir Probe, zonal drifts from the Vector Electric Field Instrument, and meridional drifts from the Ion Velocity Meter on C/NOFS show clear wavenumber-4 periodicity in the equatorial region. These wave-like structures are most prominent during deep solar minimum. Their climatology appears to be approximately similar to that of DE3 nonmigrating tides. In addition, broad plasma decreases (BPDs), deep reductions in plasma density (up to 90%) occurring over large longitudinal extents (up to 4.5 hours of local time), appear as minima in the tidal pattern on the nightside. Reductions in neutral density were observed in the same locations during the same periods of time. An analysis of ion velocities during these periods shows an unusually large average downward meridional velocity at these locations, suggesting that ion drag may be the cause of the reduction in density in both charged and neutral species.
