Salinity model errors induced by wind stress uncertainties in the Macaronesian region

According to these results, it is expected that satellite SSS data assimilation in this region will be challenging because (i) the magnitude of the SSS model error is of the same order as the accuracy of the observations, and (ii) the horizontal SSS error correlation scales are comparable to the spatial resolution of satellite SSS products. On the positive side, the temporal resolution of satellite SSS data is finer than the time scale of SSS model error growth.
