This near real-time ionospheric Total Electron Content (TEC) global map is produced at IPS by using the IRI-2007 ionospheric model with real-time foF2 data obtained from the region. You can compare this derived product with the NASA JPL Global TEC Map. Note that the IPS dervied map may lag the NASA JPL map by an hour and is centred on a different longitude.

You can also compare the IPS TEC estimate with the US Space Weather Prediction Center's CTIPe model output. "CTIPe" stands for "Coupled Thermosphere, Ionosphere, Plasmasphere and Electrodynamics". This physical model produces a world TEC map in near real time.
