Zusammenfassung |
Observations of modifications of the electron temperature in the F-region
produced by powerful high frequency radiowaves at 4.04 MHz transmitted in
X-mode are presented. The experiments were performed during quiet nighttime
conditions with low ionospheric densities so no reflections occurred.
Electron temperature enhancements of the order of 300–400 K were obtained.
Numerical simulation of ohmic heating by the pump wave reproduces both
altitude profiles and temporal dependence of the temperature modifications in
the experiments. |
