Abstract

The results of experimental studies of variations in the maximum observed fre-quency in 2016–2019 are presented on the mid-latitude route Cyprus – Rostov-on-Don. The accuracy of forecasting the maximum usable frequency when setting the state of the ionosphere using the IRI-2016 model is estimated. It is shown that in calm geophysical conditions, the typical values of the root-mean-square deviations of the maximum usable frequency from the maximum observed frequency reach 2,6 MHz.
