Ionospheric activity forecast map
The map is designed for use by those who rely on Global Navigation Satellite Systems (GNSS), users can observe and analyse ionospheric scintillation and evaluate the impact to to GNSS signals.
The below map displays Total electron content (TEC) and rate of TEC index (ROTI) values from the past seven days and forecasts TEC values for the next 48 hours. These values are updated once a day at midnight UTC. You can view specific days or set a lower limit threshold by moving the upper or lower dial on the bottom, respectively. Toggle between TEC and ROTI values and 2D and 3D views using the buttons at the top.
Map Legend:
Blue: Lower ionospheric impact
Red: Higher ionospheric impact

The TEC data was obtained through the online archives of the Crustal Dynamics Data Information System (CDDIS), NASA Goddard Space Flight Center, Greenbelt, MD, USA. https://cddis.nasa.gov/archive/gnss/products/ionex/
The ROTI data was obtained from the Ionosphere Monitoring and Prediction Center (IMPC) operated by the German Aerospace Center (DLR). We thank the DLR who maintain the IMPC services. IMPC Website: Rate of Change of TEC Index (dlr.de)
