This study assesses the dependence of atmospheric boundary layer stability on the excess emission generated by the rough ocean surface. The correction for this excess emission is one of the largest corrections required in the retrieval algorithm for sea surface salinity. Backscatter and excess rough surface emissions was found to have significant dependence on the air-sea temperature difference. The bias is clear and robust - and is, thus, suitable for an empirical correction. Additional work is needed to completely understand whether or not this is correlated with other physical mechanisms influencing the sea surface.
