Global validation of IRI TEC for high and medium solar activity conditions
Abstract
The IRI model offers a choice of options for the computation of the electron density profile and electron content TEC Recently new options for the topside electron density profile have been developed which have a strong impact on TEC Therefore it is important to test massively the IRI and these new options with experimental data A large number of permanent stations records dual frequency GPS data from which it is possible to obtain TEC values A selection of 30 worldwide distributed stations has been chosen to investigate the capabilities of the IRI to reproduce experimental TEC Different options of the model have been used to evaluate their impact focusing on F2 peak and topside models Data from the whole years 2000 and 2004 have been analysed to study the behavior of the IRI with the new topside option under high and medium solar activity conditions
