WebSatellite altimetry has revolutionized our understanding of ocean processes yet the spatial resolution of the sea surface height maps is generally limited by the wide track spacing of the repeat tracks (e.g., 300 km for the Topex/Jason series and 80 km for the ERS/Envisat/SARAL series). Here we supplement these standard measurements with … WebAuthor’s response to Anonymous Referee #2 Comments on ‘On the resolutions of ocean altimetry maps’ Anonymous Referee (AR#2): This paper: "On the resolutions of ocean altimetry maps" uses spectral coherence between SSH maps and along-track and tide gauge SSH measurements.
