Abstract:

Using the method of Rush and Gibbs 1973, weighted means of observed values have been used to update the global prediction of foF2, which are based on monthly median values derived from the Institute of Telecommunications Sciences model 1969. This procedure improved the predictions for magnetically quiet periods, for times near minimum of the solar cycle phase, and for the equinoctial months. Furthermore, a closer grid of ionosonde stations resulted in reducing the error in the foF2 prediction. For the method of Rush and Gibbs 1973 to be operationally successful in global predictions of foF2 however, a closer grid of ionosondes than is presently available is needed.
