Sea surface temperature data is produced at approximately 3 km resolution with a 15-minute duty cycle from the Spinning Enhanced Visible and InfraRed Imager on the Meteosat-9 satellite. The dataset is produced by NOAA NESDIS and covers the Indian Ocean region from June 11, 2022 to the present.
Use Cases
- Analyze SST spatial patterns across the Indian Ocean using the 3 km resolution geospatial grid.
- Track diurnal SST variability by leveraging the 15-minute temporal sampling interval.
- Assess uncertainty in SST retrievals using the included Single Sensor Error Statistics.
- Monitor SST trends from June 2022 onward for climate change impact studies.
- Validate numerical weather prediction models with forward-stream data updated every 15 minutes.
Strengths
- Data is produced at approximately 3 km spatial resolution.
- Granules are generated with a 15-minute duty cycle.
- Forward data stream is updated every 15 minutes with 3-24 hours nominal latency.
- Product follows GHRSST Data Processing Specification (GDS) version 2.0 format guidelines.
Limitations
- Granules before December 1, 2022 contain uncorrected metadata errors.
- Spatial coverage is limited to the Indian Ocean region from the satellite's position at 45.5°E.
- Specific row count, file size, and data volume are unknown.
