Herbert Oertel Jr.,Martin B?hlersal Time prediction. A series of simulation has been performed; results show that there is a significant improvement for short-term predictions (i.e. 5 or 10 days in advance) when compared to the prediction solely based on geodetic data. For longer-term prediction similar precisions are obtained.

Entwicklung von Unternehmensdatenmodellenional weather forecasting, together with the modern Earth orientation measurements, have allowed new insight into the atmospheric and non-atmospheric excitation of Earth rotation and polar motion. Recent advances are highlighted together with anticipated advances and prospects for the future.

Contribution of SLR to Earth Rotation and Terrestrial Reference Framesarisons between the terrestrial reference frames of the VLBI and SLR systems. This paper reviews the past and anticipated use of SLR in defining the terrestrial reference system and in determining rotation parameters. The potential contribution of new satellites is also considered.

Prediction of Polar Motion by Least-Squares Collocation modeling of polar motion, as was already pointed out by M.D.McCarthy (1988) and N.Sekiguchi (1988), special attention was paid to the problem of modelling and developing a procedure for determinating the parameters of the periodical and secular components.

Origin of the 30–60 Day Oscillation in the LOD and Atmospheric Angular Momentum: New Findings from teans. A coupled, zonally-symmetric mass redistribution leads to coherent fluctuations in the atmosphere’s moment of inertia. No intraseasonal oscillations are found in an experiment with surface elevations set to zero, suggesting an orographic origin of the extratropical 30–60 day AAM oscillation.
