| Abstract: | We present the results of studying the spatial and temporal correlation of the maximum observable frequency on two midlatitude
paths, Inskip (England)–Rostov-on-Don and Cyprus–Rostov-on-Don. Dynamics of variation in the maximum observable frequency
on these paths as a function of the time of the day and geophysical conditions is explored. The presence of a high spatial
correlation (up to 93.5%) between the studied maximum observable frequencies allowed the values of the maximum observable
frequency on the Cyprus–Rostov-on-Don path to be retrieved from the data on the Inskip–Rostov-on-Don path by the method of
artificial neural networks with a training efficiency of up to 97%.
