The Quasi-Biennial Vertical Oscillations at Global GPS Stations: Identification by Ensemble Empirical Mode Decomposition

Modeling nonlinear vertical components of a GPS time series is critical to separating sources contributing to mass displacements.Improved vertical precision in GPS positioning at stations for velocity fields is key to resolving the mechanism of certain geophysical phenomena.In this paper, we use ensemble empirical mode decomposition (EEMD) to analy
