Abstract
We estimate the error on the sea surface salinity (SSS) retrieved in the SMOS (Soil Moisture and Ocean Salinity) configuration at 200-km and 10-day resolution. With reasonable assumptions on wind speed errors and sea surface temperature errors, we show that the retrieved SSS should meet the GODAE requirements. The Faraday rotation is shown to affect the SSS precision by less than 15% in most oceanic regions, because of a relatively weak sensitivity of the second Stokes parameter to SSS.
