  1. SOTERIA Heliosphere and terrestrial effects SOTERIA – WP4 S. Vennerstrom And the WP4 participants

  2. WP4-Participating institutions • Hvar Observatory Croatia • MTA-KFKI-RMKI Hungary • University of Oulu Finland • Noveltis France • IEEA France • Kathoelieke Universitet Leuven Belgium • Royal Observatory of Belgium Belgium • Danish Technical University Denmark

  3. FocusA selected set of important Space Weather Parameters • CME arrival time • L1 Solar wind parameters • SEP flux • Magnetopause location • Radiation belt flux and Ring Current • Geomagnetic activity, Dst • Auroral oval position • Ionospheric Joule Heating • Ionosperic Scintillations/TEC

  4. Main Objectives • Space weather prediction of the parameters • Which are the major factors of impact? • How well does current models predict the FOCUS parameters? • Can we suggest improvements? New data assimilation schemes? • Space weather monitoring • What is the coupling between FOCUS parameters? • Can we improve current monitoring of selected FOCUS parameters (Dst, Auroral oval position) based on ESA satellite missions and ground-based data?

  5. CME/HSS arrival time L1 Solar wind parameters SEP Which are the major factors of impact? At the Sun? (Strong link to WP3, WP2) In the ambient medium in the heliosphere? How well does current models predict the parameters? Can we suggest improvements? New data assimilation schemes? Heliospheric propagation

  6. Magnetopause location Radiation belt flux and Ring Current Geomagnetic activity, Dst Auroral oval position Ionospheric Joule heating What are the major factors controlling energy partitioning? Impact on radiation level in LEO and geosynchrounous orbit Link to ”Heliospheric propagation” – Link to the Sun (WP3, WP2) Can we improve current monitoring? (Dst? Auroral oval position?) How well does current models predict the parameters? Can we suggest improvements? New data assimilation schemes? State of the magnetosphere

  7. Ionospheric scintillations during magnetic storms Morphology? Controlling factors? What is the effect on communication and navigation systems? How well does current models predict the parameters? Can we suggest improvements? New data assimilation schemes? State of the Ionosphere • Ionospheric Joule heating • Ionospheric Scintillations/TEC Source: Basu, 2002

  8. Approach Satellite Archive data Models Groundbased data New satellite missions

  9. Cross collaboration important! • We will select a limited set of events for detailed investigations (CMEs+HSSs)
