Abstract The large data base of Total Electron Content (TEC) observations which have been made over the past twenty or so years using geostationary satellites offers a very useful test of electron density models of the ionosphere, especially of the F2 region. Working on the assumption that any discrepancies between observed values of TEC and values calculated using the model N(h) profile indicate errors in the model profile, comparisons between observed and calculated values of TEC have highlighted the strengths and deficiencies of current models of the N(h) profile of the ionosphere. It is found, for example, that the Bent ionospheric model and the International Reference Ionosphere (IRI) are good descriptions of the mid-latitude ionosphere but that both fail to reproduce the observed values of the TEC at low latitudes. While it is possible to remove a large part of the discrepancies at low latitudes by ad hoc numerical adjustments to the models, it is considered that the best approach is to use theoretical models to establish accurate low latitude N(h) profiles which may be added into the empirical models.
