Analysis of Ocean Tide Loading in Differential InSAR Measurements
Ocean tide loading (OTL) causes crustal displacements in coastal regions, and the relative variation of these ground displacements may reach several centimeters across differential interferometric synthetic aperture radar (DInSAR) interferograms. However, orbit errors seriously affect the analysis of long-wavelength crustal deformation signals such as the OTL effect because of their similar sig...
متن کاملvalidation of global ocean tide models in coastal regions of persian gulf and oman sea using coastal tide gauge observations
in recent years, several ocean tide models have been used to calculate tides using data of satellite and tide gauges data. global ocean tide models have many applications in various sciences such as geophysics, geology and geodesy and oceanography. considering the existence of many models, a quantitative evaluation of research, and ranking and selecting the best model of the global ocean tide ...
متن کاملA comparison of model estimates of ocean-tide loading displacements in New Zealand
We analyze the regional accuracy of the global ocean tide models TPXO7.2, GOT00.2, NAO.99b, FES2004, and EOT10a using the tide-gauge records from 7 stations along the coastline of New Zealand. The comparison reveals that TPXO7.2 provides the bestfit with the tide-gauge data in this part of the world. The TPXO.7.2 ocean tide model is then used for computing and analysis of the vertical and horiz...
متن کاملAccuracy assessment of global barotropic ocean tide models
The accuracy of state-of-the-art global barotropic tide models is assessed using bottom pressure data, coastal tide gauges, satellite altimetry, various geodetic data on Antarctic ice shelves, and independent tracked satellite orbit perturbations. Tide models under review include empirical, purely hydrodynamic (“forward”), and assimilative dynamical, i.e., constrained by observations. Ten domin...
متن کاملMixed finite elements for global tide models
We study mixed finite element methods for the linearized rotating shallow water equations with linear drag and forcing terms. By means of a strong energy estimate for an equivalent second-order formulation for the linearized momentum, we prove long-time stability of the system without energy accumulation-the geotryptic state. A priori error estimates for the linearized momentum and free surface...
