Real-time total electron content (TEC) map over Japan

Variations of total electron contents (TECs) in Japan.

Relation between total electron contents (TEC) and delay time of propagation.
The accuracy of positioning using GPS is degraded because of variation of total electron contents (TECs) associated with geomagnetic stroms. The warning level is determined by Dst index predicted by neural network.
