This paper determines the length scales of ocean dynamics following SQG theory reachable with along-track LRM and SARM 1hz altimeter data. It relies on a joint analysis of (1) the spectral slope in the mesoscale band and (2) the noise level observed for scales lower than 20km. Maps of mesoscale capability of the on-flight LRM altimeter missions (Jason-2, SARAL/Altika, Cryosat-2) are discussed both at global and regional scales. In some oceanic areas, where available, the Cryosat-2 SARM data are also analyzed and compared to the LRM measurements.
