Comparison between measured electron density at 600 km of altitude and IRI predictions Original Research Article

The electron density at 600 Km of altitude (N600) predicted by IRI are compared with the measurements for a given particular time and place (not average) obtained with the Japanese Hinotori satellite. The results show disagreements among predictions and measurements when the model uses the CCIR and URSI options to obtain the peak characteristics. Good predictions are obtained for same cases using ground ionosonde data as input parameters in the model.
