Space climate is an interdisciplinary science that concentrates on the long-term change (tens to thousands of years) in the Sun and its effects in the heliosphere (region of space dominated by solar magnetic field), in the near-Earth space, atmosphere and climate. Space weather is concentrated on studying these things on shorter time scales from hours to few days.
In the study of space climate/space weather we utilize a wide array of different instrumentation ranging from historic records of sunspots, solar images and geomagnetic observations to more recentsatellite observations since 1960’s. More specifically our recent research has been concentrated on following key questions:
- How and why has the solar magnetic field and solar wind changed during the past 150 years?
- How have geomagnetic activity and near-Earth energetic particle populations changed during the last 150 years?
- What is causing the recent rapid decline in solar activity and what effects does it have?
- What are the solar effects on climate and climate change?
The pinnacle of this research is the Centre of Excellence on Research on Solar Long-term Variability and Effects (ReSoLVE) funded by the Academy of Finland and established in 2014. In addition to the Centre of Excellence we are tightly involved in several internationally funded projects (e.g., eHeroes, ESPAS, STORM, TOSCA).
Main people involved in the space climate research:
- prof. Kalevi Mursula, the leader of Space Climate research group and the Director of ReSoLVE
- prof. Ilya Usoskin, vice-director of ReSoLVE
- PhD/Academy Researcher Timo Asikainen
