Generation of Multi-Source Satellite SST Fusion Product of Arctic with High Temporal Resolution

High temporal resolution sea surface temperature (SST) fusion data for the Arctic were generated using optimal interpolation method with a spatial resolution of 9 km and a temporal resolution of 12 h. The accuracy of the fusion data was assessed using Argo in-situ measurements. The root mean square error (RMSE) of the fusion SST data (a temporal resolution of 12 h) ranged from 0.49°C to 0.62°C. The fusion SST data was more accurate than the AVHRR OISST data. There was no significant difference between the fusion SST data and RSS MW-IR SST data. This fusion SST data has high spatial coverage, with high temporal resolution and high precision.
