Interactive comment on “First evaluation of MyOcean altimetric data in the Arctic Ocean” by
The main objective of the paper is to analyze the quality of new My Ocean Arctic Ocean altimetry reanalysis, thanks to a comparison with others altimetry products (DUACS, RADS), model (SODA) and in-situ data (tide Gauge). As Arctic Ocean if an area of great interest for climate studies, the subject presented here could interest a large part of scientific community. The methodology described by ...
متن کاملError Estimates for an Ocean General Circulation Model from Altimeter and Acoustic Tomography Data
An offline approach is proposed for the estimation of model and data error covariance matrices whereby covariance matrices of model data residuals are ‘‘matched’’ to their theoretical expectations using familiar leastsquares methods. This covariance matching approach is both a powerful diagnostic tool for addressing theoretical questions and an efficient estimator for real data assimilation stu...
متن کاملBathymetry from Space: White paper in support of a high-resolution, ocean altimeter mission
Perhaps the most important ocean science observation in the last two decades was provided by the Geosat radar altimeter during its 18-month geodetic mission (1985-86). The declassification of these data in July of 1995 set off a flurry of activity in basic research, industrial research/development, and public interest (Appendix A). While these data fill a huge gap in our understanding of the oc...
متن کاملA comparison of ocean topography derived from the Shuttle Laser Altimeter-01 and TOPEX/POSEIDON
To assess the utility of laser altimetry for studies in dynamical oceanography, we present a comparison of the Shuttle Laser Altimeter (SLA)-01 and the TOPEX/POSEIDON (T/P) radar altimeter on global and regional scales. We compare all 1.1 million SLA-01 range measurements over the oceans to the CSRMSS95 gridded mean sea surface model and find the overall root mean square (RMS) difference to be ...
متن کاملA Physically-based Model of Ocean Backscatter for Wind Speed Retrieval from Sar, Scatterometer and Altimeter
A comprehensive theoretical model of radar backscatter from the ocean surface is discussed. It combines alternative models of the interaction between the wind and the sea surface, and different descriptions of the ocean waveheight spectrum of wind seas, with two alternative scattering theories, namely the composite-surface model and the integral equation method. The effects of swell, limited fe...
