VLF/ELF Remote Sensing of Ionospheres and Magnetospheres

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 almost 100 scientists from 21 different countries on the VERSIM mailing list.

IUGG, Sapporo, 2003

The 23rd General Assembly of the International Union of Geodesy and Geophysics (IUGG), which encompasses IAGA, was held in Sapporo, Japan, 30 June - 11 July 2003. There was a meeting of the VERSIM working group during the Sapporo Assembly, at 1900 on Monday 7 July 2003. A report on this meeting can be found here.

At this business meeting Craig Rodger (New Zealand) was nominated to take up the role of IAGA co-chairman, and elected by those present. The incoming IAGA co-chair proposed a vote of thanks on behalf of our working group to Andy Smith for all of the efforts he has undertaken to support the VERSIM community. This was supported by the meeting, and is surely agreed by the rest of the working group who could not attend.

Other forthcoming meetings

URSI, Maastricht, 2002

The 27th General Assembly of URSI was held in Maastricht, the Netherlands 17-24, August 2002. There was a meeting of the VERSIM working group during the Assembly, on 19 August 2002. A report is here.

VERSIM Newsletters

The VERSIM Newsletter (and its predecessor, the PEPM Newsletter) has been published about 1-2 times per year. Newsletters up to No. 13 were distributed on paper. From No. 14 onwards they will be distributed electronically, either via the VERSIM electronic mailing list or through this web page. Here is an archive of past VERSIM Newsletters:
