VIIRS NOAA-20: Global Sea Surface Temperature at 1-Meter Depth

NOAA-20 satellite data provides global sea surface temperature measurements at a 1-meter depth with a spatial resolution of 750 meters. The dataset, produced by the Naval Oceanographic Office using the VIIRS sensor, offers near-daily global coverage and is available from February 20, 2024. This release uses an upgraded processing algorithm with improvements in contamination and cloud detection.

Use Cases

• Modeling ocean-atmosphere heat exchange based on high-resolution sea surface temperature data.
• Monitoring daily global sea surface temperature anomalies for climate studies.
• Validating other satellite SST products based on the described comparable coverage and quality.
• Studying coastal and open ocean thermal features based on the 750-meter spatial resolution.

Strengths

• Data is derived from an upgraded processor (version 3.0) with improved contamination and cloud detection algorithms.
• Provides near-daily global coverage at a high spatial resolution of 750 meters.
• Each data file contains 768 x 3200 pixels, complying with the GHRSST GDS2 specification.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• The data record begins on February 20, 2024, which may limit long-term trend analysis.
