This research was supported in part by grants from the NASA Physical Oceanography Program (Grant # NNX14AK18G ), NASA US Participating Investigator Program (Grant # NNX17AL69G ), and Future Investigators in NASA Earth and Space Science and Technology (FINESST) Program (Grant # 80NSSC19K1326 ), and NASA Earth Science Senior Review 2017 (Grant # 80NSSC18K0534 ). SLSTR data were downloaded from the EUMETSAT Copernicus Online Data Access server at https://codarep.eumetsat.int/ . This work has benefited from discussions with Katherine A. Kilpatrick at RSMAS, and with Gary Corlett, Igor Tomazic and Jean-François Piollé at EUMETSAT, and at the GHRSST Science Team and Sentinel-3 Validation Team (S3VT) Meetings. The at-sea support by the Officers, crew, and colleagues the NOAA Ship Ronald H Brown is acknowledged. Royal Caribbean Cruises Ltd. are thanked for hosting our instruments on the Allure of the Seas, Celebrity Equinox and Adventure of the Seas.

N2 - The Skin Sea-Surface Temperature (SSTskin) derived from satellite measurements is one of the critical factors for determining ocean-atmosphere interactions in climate prediction and ocean research. Sentinel-3A is a European Earth Observation satellite mission developed to support ocean, land, and atmospheric applications. We compare three years of SSTskin from the Sea and Land Surface Temperature Radiometer (SLSTR) on board the Sentinel-3A satellite from July 2017–March 2019 with independent data from Marine-Atmospheric Emitted Radiance Interferometers (M-AERIs) deployed on research cruises. The comparison results show an average difference of −0.098 K and Robust Standard Deviation of 0.296 K between SLSTR and M-AERI SSTskin values; the average value meets the pre-launch scientific objective of a mean accuracy <0.1 K. Differences between four SSTskin retrieval algorithms have been investigated, the results show that the Dual-view 3 channels night time algorithm (D3) is better than other algorithms. This study involves determining the error and uncertainty characteristics of the SST retrievals in terms of factors that influence the accuracies of the satellite SST's, and we hope this information will be useful to improve the SLSTR atmospheric correction algorithms.
