Mediterranean Sea Daily Gap-Free Sea Surface Temperature Maps

Mediterranean Sea daily gap-free maps of sea surface temperature at a high 0.0625-degree horizontal resolution. The data are produced from satellite infrared radiometer measurements using statistical interpolation. This is the Copernicus Marine Service nominal operational product for the region, managed by POCLOUD.

Use Cases

• Analyze daily SST spatial patterns and anomalies across the Mediterranean Sea using the 0.0625-degree grid.
• Model ocean-atmosphere heat fluxes by integrating the gap-free L4 SST product with atmospheric data.
• Validate regional ocean circulation models by comparing simulated SST against the satellite-derived analysis.
• Monitor marine heatwave events by tracking temporal evolution of the interpolated sea surface temperature field.

Strengths

• Gap-free (Level 4) analysis providing complete spatial coverage daily.
• High horizontal resolution of 0.0625 degrees (approximately 1/16th degree).
• Operational product from the Copernicus Marine Service, indicating sustained production.

Limitations

• Specific temporal coverage (start/end dates) and update recency are unknown.
• Derived from infrared measurements, which can be obscured by cloud cover, though statistical interpolation mitigates this.
• Unknown spatial and temporal accuracy metrics or validation details are provided.
