3. SOTERIA SOTERIA KO ESWW 2008 Focus A 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. SOTERIA SOTERIA KO ESWW 2008 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. SOTERIA SOTERIA KO ESWW 2008 Heliospheric propagation 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?
