SOTERIA KOESWW 2008

SOTERIAFocus

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

SOTERIA KOESWW 2008

SOTERIAMain 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?

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?

SOTERIA

State of the magnetosphere• 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 Ionosphere

• Ionospheric Joule heating

• Ionospheric Scintillations/TEC

• 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?
