Topex/Poseidon Satellite Altimetry
A recently developed multiresolution estimation framework offers the possibility of highly efficient statistical analysis, interpolation, and smoothing of extremely large data sets in a multiscale fashion. This framework enjoys a number of advantages not shared by other statistically-based methods. In particular, the algorithms resulting from this framework have complexity that scales only line...
متن کاملMultivariate autoregressive modelling of sea level time series from TOPEX/Poseidon satellite altimetry
This work addresses the autoregressive modelling of sea level time series from TOPEX/Poseidon satellite altimetry mission. Datasets from remote sensing applications are typically very large and correlated both in time and space. Multivariate analysis methods are useful tools to summarise and extract information from such large space-time datasets. Multivariate autoregressive analysis is a gener...
متن کاملMonitoring Vertical Land Motions in Southwestern Taiwan with Retracked Topex/Poseidon and Jason-2 Satellite Altimetry
This study successfully uses satellite altimetry, including Topex/Poseidon and Jason-2, retrieved by novel retrackers to monitor vertical land motions in Southwestern Taiwan. Satellite altimetry was originally designed to measure open oceans, so waveform retracking should be applied to overcome the complex waveforms reflected from lands. Modified threshold and improved subwaveform threshold ret...
متن کاملCaribbean Sea eddies inferred from TOPEX/POSEIDON altimetry and a 1/6& Atlantic Ocean model simulation
Large cyclonic and anticyclonic eddies are found in the Caribbean Sea. Analysis of sea level data from the TOPEX/POSEIDON altimeter shows that the eddies are quite regular, appearing at near 3-month intervals west of the southern Lesser Antilles. These eddies progress westward at average speeds of 12 cm s, growing in amplitude up to 20 cm. Many eddies dissipate in the coastal waters of Nicaragu...
متن کاملVertical Motion determined using Satellite Altimetry and tide Gauges
A robust method to estimate vertical crustal motions by combining geocentric sea level measurements from decadal (1992 2003) TOPEX/POSEIDON satellite altimetry and long-term (> 40 years) relative sea level records from tide gauges using a novel Gauss-Markov stochastic adjustment model is presented. These results represent an improvement over a prior study (Kuo et al. 2004) in Fennoscandia, wher...
