Louisiana Wetland Water Level Monitoring Using Retracked TOPEX/POSEIDON Altimetry
Previous studies using satellite radar altimetry to observe inland river and wetland water level changes usually spatially average high-rate (10-Hz for TOPEX, 18-Hz for Envisat) measurements. Here we develop a technique to apply retracking of TOPEX waveforms by optimizing the estimated retracked gate positions using the Offset Center of Gravity retracker. This study, for the first time, utilize...
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 کاملTopex/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 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 کاملA First Comparison of Simultaneous Sea Level Measurements from Envisat, GFO, Jason-1, and TOPEX/Poseidon
The multiple altimeter missions have not only advanced our knowledge of ocean circulation, ice sheet topography, and global climate, but also improved the accuracy of altimetric measurements by cross-calibration and validation. In this paper, one year’s simultaneous maps of sea level anomaly (MSLA) data obtained from four altimeters, Envisat, Geosat Follow-On (GFO), Jason-1, and TOPEX/Poseidon ...
