Real-time Automatic Scaling and Analysis of Ionospheric Ionogram Parameters

Authors


Abstract

The real-time automatic acquisition and analysis of ionospheric parameters play important roles in monitoring and forecasting of the ionospheric space weather. For the automatic scaling and analysis of ionospheric parameters, a method based on the empirical orthogonal function (EOF) analysis of the ionospheric electron density profiles is proposed in this paper. This method is applied to the measured ionograms by CADI (Canadian Advanced Digital Ionosonde), which is set up at Beijing Space Environment Observation Station (40.3°N, 116.2°E). The results show that the method owns good reliability and universality. And this method can autoscale some ionogram parameters and reflect some related variations in ionosphere. So it can be used as a feasible tool to monitor and analyze the ionospheric space weather in real time.
