North Atlantic Sea Surface Temperature from NOAA-19 AVHRR

This dataset provides high-resolution sea surface temperature (SST) fields for the North Atlantic Region, derived from the Advanced Very High Resolution Radiometer (AVHRR) on the NOAA-19 satellite. The data is processed by the EUMETSAT Ocean and Sea Ice Satellite Application Facility, with 1km observations remapped onto a 0.02-degree grid. It is part of the international Group for High Resolution Sea Surface Temperature (GHRSST) initiative.

Use Cases

• Analyzing spatial and temporal patterns of sea surface temperature in the North Atlantic Ocean.
• Validating and calibrating regional ocean circulation and climate models using satellite-derived SST.
• Studying marine heatwaves and their impacts on North Atlantic ecosystems.
• Assimilating observational SST data into numerical weather prediction systems to improve forecast accuracy.

Strengths

• Data originates from the AVHRR sensor, which has a long operational legacy dating back to 1978, ensuring methodological consistency.
• Provides high-resolution data with a 1.1 km ground resolution at nadir, remapped to a consistent 0.02-degree grid.
• Processing includes application of a cloud mask to improve the accuracy of the retrieved SST values.

Limitations

• Specific column names, row counts, and dataset size are not provided by any source, limiting precise technical assessment.
• Conflicting 'last updated' dates exist between platforms (2013-07-04 and 2026-03-05), casting doubt on data currency and maintenance.
