Journées 2001 Systèmes de Référence Spatio-Temporels

"Influence of geophysics, time and space reference frames
on Earth rotation studies "

Brussels, Belgium,  24-26 September 2001.

The Journées 2001 Systèmes de Référence (JSR) with the sub-title "Influence of geophysics, time and space reference frames on Earth rotation studies" will be organised in Brussels (Belgium) jointly by the Royal Observatory of Belgium, the Institut d'Astronomie et de Géophysique G. Lemaître from the Catholic University of Louvain (UCL) and the Observatoire de Paris.

JSR meeting will be held at :

BBL building
1, rue du trone
B-1000 Brussels
.

The problems to be discussed in 2001 are related to various geophysical effects on Earth rotation such as geophysical fluids, tides, oceanic and atmospheric perturbations, as well as to the effects of time and space reference frames, such as time transfer, realisation of time scales and terrestrial and celestial frames. This also includes the problem of sensitivity of the different techniques of observation of Earth rotation. Earth rotation studies are also extended to other planets.
