This near real-time ionospheric total electron content (TEC) world map is produced at
IPS by using the IRI-90 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.
