GHRSST: Global Sea Surface Temperature from MetOp-B AVHRR at 8.8 km Resolution

Global sea surface temperature data derived from the Advanced Very High Resolution Radiometer on the MetOp-B satellite. The dataset is produced in real-time by the US Naval Oceanographic Office for operational oceanographic analyses and forecasts. It is based on Global Area Coverage data with a final resolution of 8.8 km.

Use Cases

• Modeling ocean heat content and climate patterns based on global sea surface temperature measurements.
• Validating and calibrating other satellite or in-situ ocean temperature data based on the AVHRR sensor's spectral bands.
• Assimilating real-time SST data into numerical weather prediction and ocean forecast models.
• Monitoring long-term sea surface temperature trends for climate change studies.

Strengths

• Data is produced in real-time for operational use, suggesting timeliness.
• Derived from the AVHRR instrument with a swath of approximately 2400 km, providing broad spatial coverage.
• Final dataset has a defined resolution of 8.8 km.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
