Abstract : The differences in critical frequencies of the ionosphere between measured values of the European continent and the model parameters of 'International Reference Ionosphere of 1990' were considered. In general, absolute relative differences of foF2 are of the order of 10 percent. They increase for twilight and night periods up to 20 or 30 percent. Relative difference for foE are less than 5 percent for day-time periods and usually are larger for twilight periods. (MM)
