IRI Model TEC Regional Map
Updates: Every 60 minutes
Displayed here is the near-real-time regional TEC map specified by the IRI2007 ionospheric model, using URSI climatological input data (fof2, M3000). The IRI2007 model is an empirical model representative of the climatological ionosphere.
Comparison of ionospheric Total Electron Content (TEC) observations with physical and/or empirical models in real time enables both an ongoing evaluation of the models under a range of ionospheric conditions, as well as providing a reference point for current ionospheric conditions, since most models are largely climatological in nature.
The model comparison pages display both the current observed conditions, the model conditions, and the difference between the two. Select a model model comparison to proceed:
