Ionospheric Heating Analysis
Abstract
The high frequency radio heating of the ionosphere running from May 1-20 has produced some surprising observational evidence of enhancements associated with the extraordinary mode of the heating radiowave (previously all other enhancements have been excited by the ordinary mode), enhanced gyro lines, and of ionospheric 'holes' burned by the heating transmitter. In the search for spectral features there has been discovered evidence for weak but measurable lines induced by the HF radio waves (O-mode) at the electron gyro-frequency and at twice the gyrofrequency. The ionospheric 'holes' are seen as extra traces on the ionograms and can be checked against electron density profiles made with the heater on and off. The anomalous heating that produces large enhancements in the intensity of the plasma line continues to attract major attention.
