摘要

We employ artificial neural networks (ANNs) to develop an algorithm yielding 1-, 2-, 3-, 12-, and 24-hour forecasts of the critical frequency of the ionospheric F_2 layer. A search for suitable training set and ANN architecture is performed. The use of auxiliary input data, such as the solar-wind and interplanetary magnetic-field parameters, as well as the geomagnetic-activity indices, makes it possible not only to improve the prediction efficiency but also to find some regularities in the critical-frequency behavior. The results of this work can be applied to the prompt correction of the ionosphere model, aimed at improving the ionospheric HF radio communication.
