📖 Accuracy of IRI- 2012 and IRI- 2001 models. In predicting total electron content.

This book contains a comparison of predicted total electron content using two international reference ionosphere models, IRI- 2012 and IRI- 2001, with observed values obtained from Athens ionograms,in order to know the accuracy of the models for predicting the total electron content over Iraq, since Athens lies in a latitude close to that of Iraq. It is found from the tables and figures of the results presented in this book, that the IRI- 2012 model is more accurate than the IRI- 2001 model for predicting the total electron content over Iraq.
