Advancements in ILWS Science: Solar Effects and Magnetospheric Studies in Finland

This presentation highlights the integral role of Finland in ILWS (International Living With a Star) activities, focusing on solar physics and its interaction with magnetospheres and ionospheres. Key areas of research include solar wind, solar energetic particles, and their impact on ground-based systems, particularly GPS disturbances. The Finnish Meteorological Institute leads initiatives such as the WARP and GUMICS-4 simulations, while collaboration with universities drives innovative space missions. Challenges and successes in public engagement and funding for space research in Finland are also discussed.

Presentation Transcript

  1. ILWS and Finland Hannu Koskinen

  2. ILWS science in Finland • Finnish Meteorological Institute, Helsinki • Magnetospheres and ionospheres • Solar wind • University of Helsinki • Solar activity and solar effects on magnetospheres • University of Turku • Solar energetic particles • University of Oulu (incl. SGO) • Solar physics, magnetosphere, ionosphere Finland and ILWS

  3. Present ILWS activities in Finland • Space • SOHO • Cluster • Ground • MIRACLE • EISCAT and SuperDARN • Simulations • GUMICS-4 • Space weather • EU COST 724 • Effects on ground • GPS disturbances Finland and ILWS

  4. Hybrid simulation variants for planetary plasma environments FMI space plasma simulations Finland and ILWS

  5. Finnish involvement in new ILWS missions • BepiColombo • Solar X-ray emissions • Solar wind - planetary interactions • Solar Orbiter • Energetic particles • Cosmic Vision 2015 – 2025 proposals • WARP (FMI lead, Tuija Pulkkinen) • Cross-Scale (strong support) • Participation in several other proposals (e.g.,IHP, EVE, Jupiter/Europa, …) Finland and ILWS

  6. WARP: Waves and relativistic particles • Four S/C constellation • 6000 km x 36000 km • equatorial (i  10 – 20 deg.) • 100 – 500 km separation • Focus on details of the inner magnetospheric physics • Full fields and particles suite on each satellite Finland and ILWS

  7. WARP: Ultimate science goal Understanding of the production of the MeV electrons in the inner magnetosphere How do plasma waves drive electron and ion acceleration, transport and loss processes ? How do the perpendicular and parallel current systems couple to plasma pressure anisotropies and gradients on the thermal ion scale ? What is the role of the structuring of EM fields and low-energy plasma environment on the distribution of the most important wave modes ? Finland and ILWS

  8. WARP and ILWS • Lead proposer: Tuija Pulkkinen, FMI • Participants from: • Austria, Belgium, Czech, Denmark, Finland, France, Germany, Greece, Sweden, UK • a good overlapping with the Cross-Scale community • Inner magnetosphere focus • different from Cluster, Themis, MMS, Cross-Scale, … • Local 4-point observations • different from RBSB, Orbitals, ERG, Resonance,… Finland and ILWS

  9. Ground-based ionospheric observations:The backbone of Finnish ILWS science Finland and ILWS

  10. Miscellaneous • IHY • Some PR activities • e.g., IHY Open Doors Day, June 10,2007 • great success, owing to a simultaneous rock concert of 60000 audience in the same park • IPY better recognized in Finland • Health of ILWS science community • Active and relatively young science community with expertise from solar eruptions to space weather effects on ground • Problems with national instrument funding • the next challenge: Solar Orbiter Finland and ILWS
