IAGA/ URSI JOINT WORKING GROUP on:
The session will take place 0830-1130, Friday 20 August 1999 and the programme will be as follows (more details):
Poster papers for these symposia are included in the joint poster session 16:30-19:00 on 19 August. Details of all the papers may be found in the Preliminary Scientific Programme and on the URSI'99 website.
Please also note the H Tutorial by L.R.O. Storey on The Measurement of Wave Distribution Functions
For more information, see: http://terezka.ufa.cas.cz/ursi/hsess.html and http://ulcar.uml.edu/ursi/URSI-98-7.html.
There are no sessions devoted specifically to VERSIM at the Assembly. At the VERSIM meeting held during the last IAGA Assembly in Uppsala (1997) it was decided not to propose a VERSIM session for Birmingham because of the proximity of URSI'99, but to consider possible topics for the 2001 IAGA in Vietnam which could be proposed at Birmingham. If anyone has suggestions for this, please let one of the co-chairman know, or come to the Business Meeting with your proposal.
The micro-satellite DEMETER (Detection of Electro-Magnetic Emissions Transmitted from Earthquake Regions) is a low-altitude satellite (< 800 km) with a nearly polar orbit. It will be the first scientific micro-satellite launched by CNES, the French National Space Agency. The expected launch date is mid-2001.
The main scientific objectives of this project are related to the investigation of ionospheric perturbations due to seismic activity, and to the global study of the Earth's electromagnetic environment. The payload of DEMETER is composed of several sensors associated with a data processing unit and a large memory in order to record the information all around the Earth independently of a telemetry station. DEMETER will measure electromagnetic waves from DC up to 4 MHz, and plasma parameters. There are two modes:

The working group on VLF/ELF Remote Sensing of the Ionosphere and Magnetosphere (VERSIM) is an international group of scientists interested in studying the behaviour of the magnetosphere and ionosphere by means of ELF (300 Hz - 3 kHz) and VLF (3-30 kHz) radio waves, both naturally and artificially generated. The group was set up in 1975 by IAGA (International Association of Geomagnetism and Aeronomy) and URSI (International Union of Radio Science), see history. Originally the emphasis was on probing of the magnetosphere by whistlers, but later the scope became somewhat broader. The group aims to promote research in this field by facilitating the exchange of ideas, information and experience between active research workers and other interested scientists. This is done through regular meetings at IAGA and URSI Assemblies, and via the circulation of a newsletter. The group has also been active in sponsoring scientific symposia at IAGA and URSI Assemblies, in areas relevant to its field of interest, and in coordinating observational campaigns. At present the main subjects of interest include Plasma structures and boundaries - morphology and dynamics, Wave-particle and wave-wave interactions, Wave-induced particle precipitation, Wave propagation in magnetosphere and ionosphere, Sprites and the effects of lightning on the ionosphere. There are currently over 100 scientists from 22 different countries on the VERSIM mailing list.
Some VERSIM Research Laboratories
URSI, Toronto, 1999
The 26th URSI General Assembly will be held in Toronto, Canada, 13-21 August 1999. For more details contact the URSI GA'99 Secretariat, National Research Council Canada, M-19, Montreal Road, Ottawa, Ontario K1A 0R6, Canada; Tel: (613) 993-7271; Fax: (613) 993-7250; email: ursi99@nrc.ca or see the WWW page: http://www.nrc.ca/confserv/ursi99.
Pitch-angle scattering (and acceleration) of trapped particles by waves in magnetospheres
This VERSIM-sponsored session (Session H3) which is a follow-up to the successful waves and the radiation belts session at Lille, broadened to include waves other than whistler mode and radiation belts other than Earth's is being convened by A.J. Smith, J. Lemaire and U.S. Inan. The deadline for submissions is now past.
There will also be two papers in the Poster Session 16:30-19:00 on 19 August.
The Plasmasphere rediscovered: a tribute to Donald Carpenter
This special workshop, convened by J. Lemaire and L.R.O. Storey will be held at the University of Toronto on Saturday 14 August 1999 in honour of Don Carpenter and his achievements in helping to discover and understand the plasmasphere and plasmapause using whistlers. Don was instrumental in founding the VERSIM group, originally known as the working group on Passive Electromagnetic Probing of the Magnetosphere. The scientific sessions both oral and poster, will be held 0830-1800 and will be followed by a banquet 1930-2400. For more details, please see http://www.magnet.oma.be/ws-h/index.html.
Other sessions for Toronto
Other sessions scheduled for URSI'99 which may be of particular interest to the VERSIM group include:
VERSIM Business meeting
There will be a meeting of the VERSIM working group during the Toronto Assembly, at 1800 on Tuesday 17 August 1999 in Room 4171, Medical Sciences Building University of Toronto. The draft agenda is: 1. Chairman's Report; 2. Future of the working group; 3. Reports from VERSIM research groups; 4. Symposia at future IAGA and URSI Assemblies; 5. Any other business. If you have any specific issues you would like to discuss, please let one of the co-chairmen know. All are welcome!
IUGG, Birmingham, 1999
The 22nd General Assembly of the International Union of Geodesy and Geophysics, which encompasses IAGA, will be held at the University of Birmingham, UK, 19-30 July 1999. The scientific programme and information on how to register for the assembly may be found on the Web site: http://www.bham.ac.uk/IUGG99/, or contact the organising committee at email: IUGG99@bham.ac.uk or fax: +44 121 414 4942.
VERSIM Business meeting
There will be a meeting of the VERSIM working group during the Birmingham Assembly, on the evening of {Tuesday 20 July 1999 (venue to be announced). The draft agenda is the same as for the Toronto meeting given above. All are welcome!
IAGA, Hanoi, 2001
The 9th Scientific Assembly of IAGA will be held in Hanoi, Vietnam, 18-30 August 2001. Some details about the venue were given in IAGA News, No. 38 (October 1998)
