Introduction:

The team holds 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;
  • development of new methods to data analysis to predict solar variability.
  • Solar-cycle evolution of meridional circulation and differential rotation for solar dynamo modeling.

Action plan:

  • biannual meeting or telecons on coordination of efforts in studying of long-term solar variability;
  • community-wise study of solar cycle variability for the last millennium using new proxy data;
  • development of an information portal for existing diverse data sources;

Clusters with overlapping topics:

S2, H1
