| Zusammenfassung |
| Low-frequency electrostatic fluctuations in
the ionospheric E region were detected by instruments on the ROSE rockets. The
phase velocity and dispersion of plasma waves in the ionospheric E region are
determined by band-pass filtering and cross-correlating data of the
electric-field fluctuations detected by the probes on the ROSE F4 rocket. The
results were confirmed by a different method of analysis of the same data. The
results show that the waves propagate in the Hall-current direction with a
velocity somewhat below the ion sound speed obtained for ionospheric conditions
during the flight. It is also found that the waves are dispersive, with the
longest wavelengths propagating with the lowest velocity. |
