Altimeter; Monthly mapsAbstract
Monthly Maps of sea surface height are constructed for the North Atlantic Ocean using TOPEX/Poseidon altimeter data,
Mean sea surface height is reconstructed using a weighted combination of historical, hydrographic data and a synthetic
mean obtained by fitting a Gaussian model of the Gulf Stream jet to altimeter data. The resultant mean shows increased
resolution over the hydrographic mean, and incorporates recirculation information that is absent in the synthetic mean.
Monthly maps, obtained by adding the mean field to altimeter sea surface height residuals, are used to derive a set of zonal
indices that describe the annual cycle of meandering as well as position and strength of the Gulf Stream.

A new approach to estimation of global air-sea gas transfer velocity fields using dual-frequency altimeter backscatter
Frew, Nelson M.; Glover, David M.; Bock, Erik J.; McCue, Scott J. (American Geophysical Union, 2007-11-03)A new approach to estimating air-sea gas transfer velocities based on normalized backscatter from the dual-frequency TOPEX and Jason-1 altimeters is described. The differential scattering of Ku-band (13.6 GHz) and C-band ... -
Improving the time resolution of surfzone bathymetry using in situ altimeters
Moulton, Melissa; Elgar, Steve; Raubenheimer, Britt (2013-06)Surfzone bathymetry often is resolved poorly in time because watercraft surveys cannot be performed when waves are large, and remote sensing techniques have limited vertical accuracy. However, accurate high-frequency ...
