WP4 - Heliospheric propagation and terestrial effects
Objectives
- To investigate the effect of different regular structures and eruptions of the solar magnetic field on near Earth solar wind parameters and energetic particle fluxes and their terrestrial impact
- To develop new methods for diagnosing the state of the magnetosphere and space weather based on magnetic and energetic particle observations
- To validate and improve existing space weather models
- To improve existing capability and develop new methods for space weather forecasting, including data assimilation
Participants
IEEA, KULeuven, DTU, Uoulu, MTA-KFKI-RMKI, Noveltis, HVAR, ROB, LPI
Approach and organization
Event studies
Due to the “chain reaction” nature of the investigated processes the work was initiated by selecting a number of events for which data is being collected, theoretical simulation runs performed and the various aspects studied simultaneously by all participants.
Focus parameters
In order to focus the effort, a set of space weather relevant focus parameters have been selected:
- CME arrival time
- L1 Solar wind parameters
- SEP flux
- Magnetopause location
- Radiation belt flux and Ring Current
- Geomagnetic activity, Dst, Kp
- Auroral oval position
- Ionospheric Joule Heating
- Ionosperic Scintillations/TEC
