The principal aim of the workshop is the production of a volume to be published in the Space Sciences Series of ISSI by Springer Verlag. This volume is *not* intended to be the proceedings of the workshop, but will provide a coherent collection of in-depth papers informed by the presentations and discussions at the workshop. All of those attending will be expected to contribute to one or more of the chapters.
The volume will give an overview of the current state of our subject and it is our ambition that it will become a reference book for a considerable period of time. All papers will be peer-reviewed and, in addition the book, be published individually in the journal Space Science Reviews as a Topical Collection. We expect that the papers will be submitted within 3 months of the workshop. The journal issue and the volume are expected to appear within 12-18 months after the workshop.
