IRI model performance evaluation for the Mexican region

Here, we illustrate the modeling and experimental results for vertical Total Electron Content (TEC) over Mexico during the five year period 2018 2022. The results were obtained for the U COE GNSS receiver station (geographic coordinate s: 19.6°N; 101.68°W ). The calculations were made each two hours during the whole period unde considerations. The modeling results were obtain ed using the "International Reference Ionosphere (IRI)" model, which is an empiric al climatological model based on ground and space observations of the ionosphere [Bilitza et al., 2022].
