Session - Key solar observables for assessing long-term changes of the Geospace

Thierry Dudok de Wit, M. Haberreiter, A. Seppälä

Our understanding of long-term changes in the Heliosphere, and their potential impact on the Earth's climate, heavily relies on our ability to reconstruct past solar activity, on time scales of months to centuries. Most observables of past solar activity, such as the sunspot number, geomagnetic records, and cosmogenic isotope concentrations, are indirect, and thus rely on models to infer the state of the Sun. In recent years, major progress has been made in the collection of historic data, in their (re)analysis, thus shedding new light on how the Sun evolves on the long term.

We welcome contributions on the observables that describe the solar forcing of our Geospace, with a particular emphasis on long-term effects, and the impact on climate. Particular attention will be given to recent advances in the collection or understanding of these observables, but also important open issues, and roads for future improvement.

This session will have oral presentations (contributed and invited reviews), but we're also looking forward to going more in depth with an active and well-attended poster session. We welcome posters on important observables for climate research, including more technical and user-oriented issues such as data collection, data processing and the making of composites, how and where the data are available, how stable they are on the long run, etc.
