  Information - ST8 Coupling between regions and scales: the future is multipoint and multi-instrument

Event Information
Understanding of fundamental dynamic, 3D plasma processes in solar-terrestrial physics inevitably requires simultaneous multipoint observations with high quality multi-instrument observations at each of those points. In recent years the co-ordination between Cluster, Double Star, Geotail and networks of ground-based systems, such as SuperDARN, arrays of magnetometers and optical instruments have been particularly successful.

However, such coordination sometimes is very complex technically. Combining data from multiple spacecrafts with data from the ground-based instrumentation as well as modeling requires new ideas for visualization, data sharing, assimilation and presentation. There is a need to address and identify future challenges in observations and data analysis enhanced by numerical modeling, when we look forward to missions such as MMS, Themis and the initiative for the Distributed Array of Small Instruments (DASI).

Furthermore, understanding of fundamental plasma processes and space plasma dynamics requires simultaneous observations on different scales, from global to electron and ion scales, to study the manner in which different phenomena and scales couple with one another in a feedback loop. This coupling is important across a broad range of terrestrial and astrophysical applications. The Cross-Scale mission within ESA Cosmic Vision plan can give us these answers. There is a need to identify and refine the key science drivers for Cross-Scale and the constraints imposed by technical considerations.

This session is open to papers, which highlight the application of and/or requirements for present and future multi-instrument multi-spacecraft science. Observational, theoretical, and simulation results together with data analysis methods, technical and operational studies are all welcome.
