Abstract :
The authors describe one of the outstanding limitations on the use of satellite radar altimeter height measurements for determining the topography of the sea surface and consequently the geostrophic ocean surface currents. The presence of waves on the sea surface introduces a bias, known as the sea state bias, in the altimetric height measurement. Although this bias is small, of the order of centimetres, it is of a similar order to the accuracy necessary for determining the sea surface topography
