TL;DR: A new data filtering method, based on the Vondrak filter and the technique of cross-validation, is developed for separating signals from noise in data series, and applied to mitigate GPS multipath effects in applications such as deformation monitoring.

TL;DR: Tide gauge records of Hong Kong covering the past 45 years (19540-19990) are adopted to analyze the basic features of sea level changes in the region Data sets of atmospheric pressure, southern oscillation index and sea surface temperature during the same time span are also used to determine the possible link between the sea level change in Hong Kong and local and global geophysical processes.

TL;DR: The application of the LSTSA model improves the wavelet time–frequency spectrum, especially enhancing the ability to detect the low-frequency signals.

TL;DR: In this paper, the authors analyzed the non-atmospheric LOD excitation contributed by the Western Pacific Warm Pool (WPWP) during the period of 1970-2000, and found that the positive effects of the WPWP on the interannual LOD variation are found, although the scale of the warm pool is much smaller than that of the solid Earth.

TL;DR: In this article, a time series of daily position solutions at eight co-located GPS and VLBI stations is used to assess the frequency features in the solutions over various time-scales.
