Paper Abstract

The IRI model provides a step-like dependence of the relative ion composition over an annual cycle which is determined by three seasons. Variations over a cycle of solar activity are given only for two steps of low and high activity. We suggest an approximation of seasonally-cyclic variations in relative content of molecular ions to give a smooth continuous dependence on the day of the year and on the index of solar activity F10.7.
