| Zusammenfassung |
| Observations of airglow at 630nm (red line) and 557.7nm (green line)
during HF modification experiments at the High Frequency Active Auroral
Research Program (HAARP) heating facility are analyzed. We propose a
theoretical framework for understanding the generation of Langmuir and ion
acoustic waves during magnetic zenith injections. We show that observations
of HF-induced airglow in an underdense ionosphere as well as a decrease in
the height of the emitting volume are consistent with this scenario. |
