Abstract Empirical models such as the International Reference Ionosphere (IRI) are synthesized from large data bases. They can be viewed as analytical tools to facilitate accessing information stored in the data banks. However, in establishing the models, one has to apply smoothing and averaging procedures that in effect reduce the original information content. Our study evaluates the agreement between the data base and the model at two opposite extremes of time resolution. We compare electron densities and temperatures in the altitude range of 300 to 400 km predicted by the IRI and measured by the AE-C and DE 2 satellites on the level of individual orbits as well as on the level of mission averages. Whereas the averages show excellent agreement, the comparison for individual measurements indicates the limitations of empirical models.
