--------------------------------------------------------------------- 3. CALL FOR PAPERS - EUROPEAN GEOPHYSICAL SOCIETY XX GENERAL ASSEMBLY --------------------------------------------------------------------- From: Alan Rodger (ASRO@pcmail.nerc-bas.ac.uk) EUROPEAN GEOPHYSICAL SOCIETY XX General Assembly Hamburg, 3-7 April 1995 Call for Papers Session: ST3 Title: OPEN SESSION ON THE IONOSPHERE AND THERMOSPHERE Scope of Session: This session is suitable for contributions on all aspects of the ionospheric or thermospheric physics which are not treated in other sessions: for example ST6 (The ionosphere one its Coupling with the Magnetosphere and the Thermosphere), ST7 (Substorms), ST8 (Small Scale Plasma Structures in the Ionosphere and Magnetosphere). Topics to be considered include experimental and modelling studies of the structure and dynamics at large or local scales in the ionosphere or in the thermosphere. Name and Address of Convenor(s): Dominique Fontaine CETP-CNRS, Centre Universitaire, 10-12 Avenue de l'Europe, 78140 V?lizy, France; Tel: +33-1-39 25 49 17; Fax: +33-1-39 25 49 22; E-mail: DOMINIQUE.FONTAINE@CETP.IPSL.FR Session: ST4 Title: OPEN SESSION ON THE MAGNETOSPHERE Scope of Session: The objective of the symposium is to provide a forum for papers on magnetospheric topics that do not fit in the specialist symposia, ST6, ST7 and ST8. Name and Address of Convener: Professor Michael J Rycroft College of Aeronautics, Cranfield University, Cranfield, BedfordMK43 0AL, UK Session: ST6 Title: THE IONOSPHERE AND ITS COUPLING WITH THE MAGNETOSPHERE AND THE THERMOSPHERE Scope of Session: The terrestrial ionosphere, especially in the auroral and polar regions, interacts strongly with the magnetosphere (Charge particle precipitation and plasma outflow, transmission of electric fields, current circuits), and with the thermosphere (atmospheric dynamo, collisions). The scope of this session is to discuss different aspects of these coupling mechanisms from the large scale down to the small scale (acceleration, heating, instabilities, ...). Papers on relevant observations from ground-based instruments and from satellites (FREJA, ...) are welcome, as are those on theory, modelling or simulations.

Despite significant progress in recent years and the development of revised hypotheses, such as the Kiruna conjecture, there are still many major uncertainties over many substorm processes. These include the location and cause of the cross-tail current disruption that marks the onset of the expansion phase, and what part, if any, enhanced reconnection in the tail plays in the substorm process. The symposium seeks to address issues associated with all three phases of the substorm both in the tail of the magnetosphere and in the ionosphere. It is likely to include presentations of ground-based and satellite observations, theory, modelling and simulations.

The term "small scale" certainly refers to different scales in the different regions. In the magnetosphere structures smaller than the scale of an auroral arc will be regarded. Examples of such small scale structures are the solitary structures, shown by recent satellite measurements toexist in rich abundance and variety, and under study both theoretically and by computer simulations. In the ionosphere structures smaller than a few kilometres (e.g. excluding TIDs, gravity waves etc.) will be regarded. Papers on common experimental techniques as well as on theoretical treatments or modelling will be welcome. Also processes involving dusty plasma (e.g. PMSE related phenomena) will be included in the scope of the session.
