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), as described in the working group 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 about 26 different countries on the VERSIM mailing list.

Other forthcoming meetings

URSI, New Delhi, 2005

The 28th General Assembly of URSI was held in New Delhi, India 23-29, October 2005. There was a meeting of the VERSIM working group during the Assembly, on Wednesday 26 October 2005. A report on this meeting is available here.

IAGA, Toulouse, 2005

The IAGA Scientific Assembly was held in Toulouse, France from 18-29 July 2005. There was a meeting of the VERSIM Working Group during the Toulouse Assembly, at 1715 on Thursday 21 July 2005. A report on this meeting can be found here. Note that the next gathering will be the 24rd General Assembly of the International Union of Geodesy and Geophysics (IUGG), which encompasses IAGA, to be held in Perugia, Italy, over 2-13 July 2007.

SGO VLF Workshop, Sodankylä, 2004

The first VLF Workshop was held at the Sodankylä Geophysical Observatory, Finland from 27th September to 1st October 2004, sponsored by URSI Commission H and supported by the VERSIM IAGA/URSI joint working group. There was a meeting of the VERSIM working group during the 2004 SGO VLF Workshop, at 1500 on Wednesday 29 September 2004. A report on the VERSIM meeting can be found here.

 The facilities and organisation of this workshop was of a very high standard, and at the end of the 2004 Workshop the participants gave a vote of thanks to the Local Organising Committee for running the workshop so smoothly. Their efforts ranged from keeping the timetable realistic and picking up people at the airport to arranging for some of Sodankylä's souvenir shops and restaurants to open late for workshop participants. A full report on the 2004 SGO VLF Workshop, which discusses plans for future VLF workshops is available.
