The MUIR UHF radar at the HAARP ionospheric modification facility has been operated in a number of experiments where the HF-enhanced ion-line has been used to monitor the ionospheric density variations. The altitude of the enhanced ion-line signals moves downward in response to increasing electron density variations that result from temperature-dependent ion chemistry, and for the special gyro-resonant case additional ionization is produced due to local electron acceleration near the altitudedoi:10.1109/ursigass.2011.6051131 fatcat:jtpkkpyhr5asnihavpiot4m6y4
