The ionospheric vertical Total Electron Content (TEC) and its variability were estimated every 15 minutes on a 0.5°x0.5° grid. This service delivered IONEX TEC products https://gnss.be/SpaceWeather/Products/IONEX/ and a web service highlighting the ionospheric activity at https://gnss.be/SpaceWeather/index.php. This dataset is now discontinued and replaced by the European near-real-time ionosphere TEC maps based on multi-GNSS observations, since the 17th May 2025.
