Team title: Long-term solar variability Team ID: S1-01 Team Lead: Ilya Usoskin (University of Oulu, Finland), ilya.usoskin@oulu.fi Participants: Ilya Usoskin (University of Oulu, Finland), ilya.usoskin@oulu.fi Hisashi Hayakawa (STFC Rutherford Appleton Laboratory, UK), hisashi.hayakawa@stfc.ac.uk Mathew Owens ( University of Reading, UK), m.j.owens@reading.ac.uk Keywords: Introduction: The team holds a top-level expertise in long-term solar activity reconstruction based on sunspot observations; cosmogenic proxy data; extreme solar events; cosmic-ray modulation; cosmic-ray effects in the atmosphere; long-term solar variability. Objectives: Reliable estimates of long-term solar variability, based on proxy data, including uncertainty assessments. Action topics: Extreme space weather events and their impacts, Solar irradiance, open flux and solar wind reconstruction, Solar activity indices for constraining long-term variability Clusters with overlapping topics: S2, H1 Link to team external website:
