Thermal Imaging of Marine Areas–1 with SENTINEL-3
The Sea and Land Surface Temperature Radiometer (SLSTR) sensor records radiation in the VNIR, SWIR and TIR ranges. Up to L2 level, the data are processed separately for the land and sea area. Products for the sea area containing sea surface temperature data are only available through EUMETSAT services.
Find the information on how to view and obtain SLSTR sensor data (Sentinel-3) for the sea area and how to prepare it for further work in GIS using SNAP in the link below (in Polish).
