GHRSST L2P MSG02 SST: Indian Ocean Sea Surface Temperature at 3 km Resolution

Indian Ocean region sea surface temperature data from the Meteosat-9 satellite's SEVIRI instrument. The dataset provides measurements at approximately 3 km resolution with a 15-minute duty cycle, produced by NOAA NESDIS. Data coverage begins June 11, 2022 and is updated every 15 minutes with a nominal latency of 3-24 hours.

Use Cases

• Modeling ocean-atmosphere heat exchange based on high-frequency skin sea surface temperature measurements.
• Monitoring diurnal warming cycles in the Indian Ocean based on the 15-minute data duty cycle.
• Assimilating satellite SST data into numerical weather prediction models based on the GHRSST GDS 2.0 format.
• Studying regional climate variability and trends based on the continuous data stream from June 2022 onward.

Strengths

• High temporal resolution with data updates every 15 minutes.
• Spatial resolution of approximately 3 kilometers.
• Includes Single Sensor Error Statistics (uncertainty metrics) following the GHRSST GDS 2.0 specification.
• Continuous forward data stream with coverage from June 11, 2022 to the present.

Limitations

• Granules before December 1, 2022 contain some uncorrected metadata errors.
• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
