Multi-Sensor Sea Surface Temperature Map for a Single Day

A single 24-hour period of sea surface temperature data derived from multiple satellite sensors. The product is a 0.02-degree resolution map covering the region from 70E to 170W and 20N to 70S, composited from VIIRS and AVHRR sensor data. It is provided by the Australian Ocean Data Network (AODN) under a CC-BY-4.0 license.

Use Cases

• Modeling ocean heat transport based on daily sea surface temperature averages.
• Analyzing regional temperature anomalies based on the 0.02-degree resolution grid.
• Calibrating satellite sensor algorithms based on the multi-sensor compositing method described.
• Studying diurnal sea surface temperature variations based on the separate day and night time processing.

Strengths

• Data is derived from multiple satellite sensors (VIIRS and AVHRR), likely increasing coverage.
• The product uses a specific 0.02-degree x 0.02-degree cylindrical equidistant projection.
• Quality levels are remapped using Sensor Specific Error Statistics (SSES) as per a referenced methodology.

Limitations

• Row count and dataset size are unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Last update date is unknown; freshness unverified.
