GHRSST Level 2P: Regional 1m Sea Surface Temperature from NOAA-19 AVHRR

NOAA-19 satellite data provides sea surface temperature retrievals from the Advanced Very High Resolution Radiometer, launched in February 2009. The dataset is produced operationally by the US Naval Oceanographic Office from Local Area Coverage data, binned to a final resolution of 2.2 km. Coverage generally includes ocean scenes adjacent to Australia and the North Indian Ocean.

Use Cases

• Modeling regional ocean heat content based on multi-channel thermal radiation measurements.
• Validating sea surface temperature forecasts based on real-time satellite retrievals.
• Analyzing diurnal temperature cycles based on twice-daily sun-synchronous satellite views.
• Studying coastal ocean dynamics based on high-resolution 1.1 km nadir data.

Strengths

• Data is produced and used operationally by the US Naval Oceanographic Office (NAVO).
• Sensor provides a swath width of approximately 2400 km and a highest ground resolution of 1.1 km at nadir.
• Derived from the AVHRR/3 instrument which includes a 6th spectral channel at 1.6 micrometer.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Coverage is regional and can vary, focusing on areas near Australia and the North Indian Ocean.
