Extrapolation of the Maximum Usable Frequency by Adapting the Ionospheric IRI-2007 Model According to Oblique Sounding Data in the Euro-Asian Region

We present the results of prediction and extrapolation of the maximum usable frequency (MUF) on the subauroral and midlatitude paths of the Euro-Asian region by adapting the reference ionosphere model IRI-2007 based on the results of the oblique chirp sounding of the ionosphere on the reference and...

Summary:We present the results of prediction and extrapolation of the maximum usable frequency (MUF) on the subauroral and midlatitude paths of the Euro-Asian region by adapting the reference ionosphere model IRI-2007 based on the results of the oblique chirp sounding of the ionosphere on the reference and working radio links. It is shown that under conditions of a quiet ionosphere where the adapted ionospheric model is used, the errors of the MUF prediction on the reference path and the error of the MUF extrapolation to the neighboring paths not equipped with diagnostic tools are 2–8%, which is significantly less than the long-term prediction data which amount to 9–20% [ 1 – 3 ].
