Australian Vessel Sea Surface Temperature Sensor Data in Near Real-Time

Near real-time sea surface temperature data is supplied within 24 hours from ships of opportunity and research vessels worldwide. Seven vessels, including five from the Australian Volunteer Observing Fleet and two with specialized systems, collect hourly bulk SST data across the Southern Ocean, Australian coast, and Pacific. All data undergoes quality assurance and is fed into the Bureau of Meteorology's satellite validation system and operational SST analyses.

Use Cases

• Calibrating and validating satellite-derived sea surface temperature data based on high-quality in-situ observations.
• Improving spatial and temporal coverage for ocean models in data-sparse regions like the Western Pacific Tropical Warm Pool and Southern Ocean.
• Feeding operational regional and global SST analyses based on data distributed via the Global Telecommunications System.

Strengths

• Data is supplied in near real-time, typically within 24 hours of collection.
• Sensors include high-accuracy Sea Bird SBE 48 and SBE 38 models on multiple vessels.
• Quality assurance is performed before data is placed on the Global Telecommunications System.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• Historical data from four vessels mentioned in the description is not available in real-time.
