This paper reports the first statistical analysis of this dataset with variance maps, spectra, auto-correlation and space / time scales that are consistent with past observations. Our results highlights the value of this Jason-1 GM overlap dataset for more sophisticated studies of the rapid ocean variability, but also two major limitations: 1/ the noise level of Jason-class altimeters prevents from analyzing scales smaller than 80 km, and 2/ short time differences also absorb a fraction of the derivative of slower signals.
