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
12.6.2007Finland and ILWS 3
Present ILWS activities in Finland• Space
• SOHO
• Cluster

FMI space plasma simulations
Hybrid simulation variants forplanetary plasma environments
12.6.2007Finland 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, …)
12.6.2007Finland 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
12.6.2007Finland 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 ?
12.6.2007Finland 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,…
12.6.2007Finland and ILWS 9
Ground-based ionospheric observations:The backbone of Finnish ILWS science
12.6.2007Finland 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
