Abstract:
We present results of the analysis of Earth rotation data derived from the continuous very long baseline interferometry (VLBI) campaign CONT02. The high-frequency contents of polar motion and UT1 are analyzed and compared to theoretical models. We perform signal analysis using Lomb periodograms, Wavelet analysis and a modified Fourier analysis. We find a ter-diurnal variation in polar motion close to the S3 tide constituent. © 2005 Elsevier Ltd. All rights reserved.
