Last 24 hours of ionospheric total electron content (TEC) world maps are produced at TACC by using the TEC between 80 km and top collected from the FORMOSAT-3/COSMIC. The bottom locations of occultations are marked as the black dots in the map, the total number of occultations is displayed above the map.

The maps are designed to give a quicklook of the global TEC. NOTE the TEC values should be treated with caution. Questions and Comments : TACC webmaster
