Rate of change of TEC index - Global

The Rate of change of TEC index (ROTI) can be used as a measure to detect disturbances in the ionosphere.

We calculate the ROTI from real-time data streams and associate the calculated values to the ionospheric pierce points. The world map is overlaid with a grid and the averaged ROTI values falling in a certain tile are shown.
