The Skin Sea Surface Temperature (SSTskin) derived from satellite measurements and models is one of the key factors for studying ocean-atmosphere interactions for climate prediction and ocean modeling research. SENTINEL-3a ad 3b are a pair of a European Earth Observation satellite missions developed to support ocean, land, atmospheric applications. Each satellite carries a Sea and Land Surface Temperature Radiometer (SLSTR). We compare SSTskin derived from measurements of the SLSTR on board the Sentinel-3a satellite with independent measurements of Marine-Atmospheric Emitted Radiance Interferometers (M-AERIs) deployed on ships during the Aerosols and Ocean Science Expeditions (AEROSE) cruises. The comparison results reveal a small average difference of ~0.06K and median difference of 0.005K between SLSTR and M-AERI. This research indicates some improvements to the algorithms to derive SSTskin from measurements of the SLSTR.
