Comparison of Sentinel-3 Slstr Sst Product with Shipboard Skin Sst Measurements

Sea surface temperature (SST) is an important indicator for climate change. Nowadays many sensors in orbit have the capacity of SST observations. Long-term climate data record of global SST requires satellite SST products with high accuracy and stability. In order to evaluate the quality of satellite SST products, proper collection of in situ sea surface skin temperature is needed. The infrared SST autonomous radiometer (ISAR) has been deployed on the research vessel Dong Fang Hong II of Ocean University of China since 2009. The ISAR data collected during five cruises are used to validate the Level-2 WST products from Sea and Land Surface Temperature Radiometer (SLSTR). The comparison results show negative bias of 0.085K and standard deviation of 0.356K. Due to the influence of the weather conditions and short temporal extent of the SLSTR L2 WST archived, only 148 match-ups are produced. Further studies will be carried out with more available data from in situ and satellites.
