Abstract
Over the last two decades, several nadir profiling radar altimeters have provided our first global look at the ocean basinscale circulation and the ocean mesoscale at wavelengths longer than 100 km. Due to sampling limitations, nadir altimetry is unable to resolve the small wavelength ocean mesoscale and sub-mesoscale that are responsible for the vertical mixing of ocean heat and gases and the dissipation of kinetic energy from large to small scales. The Surface Water and Ocean Topography (SWOT) mission being considered by NASA has as one of its main goals the measurement of ocean topography with kilometer-scale spatial resolution and centimeter scale accuracy. In this paper, we provide an overview of all error sources that contribute to the SWOT mission for the ocean. This paper is a sequel to an earlier paper describing the SWOT mission, the science and its payload.
