Ionosphere Monitoring and Prediction Center

The Ionosphere Monitoring and Prediction Center (IMPC) of DLR provides a near real-time information and data service for the current state of the ionosphere, related forecasts and warnings. It benefits from the strong expertise in ionospheric science and expert knowledge on data management and archiving of two DLR institutes.

Well established ground and space based GNSS measurements offer a unique chance to permanently monitor the electron density and its structure of the ionosphere-plasmasphere system. IMPC uses of them to generate products reflecting the current state ionosphere and related forecasts, which are disseminated via the website A subset is provided here to the ESA Space Weather Service Portal.
