GHRSST L2P MSG01 SST: Indian Ocean Sea Surface Temperature from Meteosat-8, 2018-2022

Indian Ocean region sea surface temperature data at approximately 3 km resolution, produced by NOAA NESDIS from the SEVIRI instrument on the Meteosat-8 satellite. The dataset provides full-disk imagery with a 15-minute duty cycle and includes Single Sensor Error Statistics, following GHRSST GDS 2.0 format guidelines. Records span from September 18, 2018, to June 1, 2022.

Use Cases

• Modeling ocean-atmosphere heat exchange based on high-frequency sea surface temperature measurements.
• Studying diurnal warming cycles in the Indian Ocean based on the 15-minute data duty cycle.
• Assimilating satellite-derived SST into weather and climate forecast models based on the GHRSST-compliant data product.
• Analyzing regional climate variability and marine heatwaves based on the 3 km resolution spatial data.

Strengths

• Provides a specific temporal coverage from September 18, 2018, to June 1, 2022.
• Features high temporal resolution with a 15-minute duty cycle.
• Includes Single Sensor Error Statistics (uncertainty metrics) following the GHRSST GDS 2.0 specification.

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.
