GHRSST Level 2P: Atlantic Regional Sea Surface Temperature from Meteosat-9

GHRSST Level 2P data provides skin sea surface temperature (SST) measurements derived from the SEVIRI instrument on the Meteosat-9 satellite. The dataset is produced by NOAA NESDIS following the GHRSST-PP Data Processing Specification version 2.0, offering observations at approximately 5 km resolution with a 15-minute duty cycle.

Use Cases

• Modeling ocean heat flux and climate patterns based on high-frequency, regional SST observations.
• Validating global climate models based on geostationary satellite-derived skin temperature data.
• Monitoring diurnal warming cycles in the Atlantic Ocean based on the 15-minute temporal resolution.
• Assimilating near-real-time SST data into numerical weather prediction models.

Strengths

• Data is derived from a geostationary satellite providing a 15-minute observation duty cycle.
• SST is calculated at full resolution from 8 thermal infrared channels.
• Products include Single Sensor Error Statistics (SSES) following the GHRSST-PP GDS version 2.0 specification.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and total dataset size are unknown, which may limit suitability assessment.
• The spatial coverage is specified only as 'Atlantic Regional'; exact boundaries are not detailed.
