GHRSST Level 3C: GOES-13 Sea Surface Temperature for the Americas

GHRSST Level 3C sub-skin Sea Surface Temperature from the Geostationary Operational Environmental Satellites (GOES 13) Imager in East position produced by OSI SAF (GDS version 2). This dataset provides near-real-time, gridded sea surface temperature measurements for the Americas region, derived from infrared channels on the GOES-13 satellite. The data is processed every 30 minutes and remapped to a 0.05-degree regular grid spanning 60S-60N and 135W-15W.

Use Cases

• Monitoring diurnal sea surface temperature variability based on the 30-minute temporal resolution.
• Assimilating near-real-time SST fields into numerical weather prediction models based on the operational product description.
• Studying regional ocean-atmosphere interactions in the Americas using the geospatially gridded data.
• Correcting regional and seasonal biases in satellite SST retrievals using the described atmospheric profile correction method.

Strengths

• Data is produced in near real time, supporting operational monitoring.
• Spatial resolution is high at a 0.05-degree regular grid.
• Algorithm corrects for regional and seasonal biases using atmospheric profiles from a numerical weather model.

Limitations

• SST retrieval is not possible in daytime conditions due to the lack of a 12-micrometer channel on the GOES-13 imager.
• Metadata completeness is low: row counts, file sizes, and specific column names are unknown across all sources.
• There is a conflict in dataset freshness: one source lists a last updated date in 2026, while another lists 2017, casting doubt on current operational status.
