Observations of the Heating Experiments in the Polar Winter Ionosphere III–Analysis in the Low Region

Abstract

Under the condition of ionosphere heating in the low region, the theoretical incoherent scatter model with the non-Maxwellian distribution in collisional plasma is presented, and the measured data in polar winter ionospheric modification experiments carried out in January 2008 at Tromsø are analyzed. The obvious electron temperature enhancement can be seen in this experiment, and the maximum percentage is up to 168.9%. The non-Maxwellian index is also given, and the heating electric field is deduced from the index, which has important meaning for numerical simulation of the artificial ionospheric modification.
