Atlantic Sea Surface Temperature from Meteosat SEVIRI Satellite

Satellite-derived skin sea surface temperature data for the Atlantic region is provided every 15 minutes at approximately 5 km resolution. The dataset is produced by NOAA NESDIS from the SEVIRI instrument on the Meteosat-9 satellite, following the GHRSST Data Processing Specification version 2.0. It represents Level 2P data products with Single Sensor Error Statistics.

Use Cases

• Monitoring diurnal and seasonal sea surface temperature cycles in the Atlantic Ocean using the 15-minute interval SST measurements.
• Validating and calibrating ocean circulation and climate models with spatially continuous SST fields at 5 km resolution.
• Assimilating near-real-time skin SST data from the SEVIRI infrared channels into numerical weather prediction systems.
• Analyzing SST anomalies and marine heat wave events using the long-term record from the Meteosat-9 satellite launched in 2005.

Strengths

• High temporal resolution with observations generated every 15 minutes, enabling the study of diurnal warming cycles.
• Standardized processing following the international GHRSST-PP Data Processing Specification (GDS) version 2.0, ensuring interoperability.

Limitations

• Specific row count, file size, and complete column schema are not provided by any source, limiting precise technical assessment.
• Conflicting 'last updated' dates exist between sources (2018-02-20 and 2026-03-05), creating uncertainty about data currency.
