Near real-time and historical sea surface temperature data collected from 12 vessels in the Australian region, including research ships and volunteer observing fleet vessels. The dataset is produced by the Australian Ocean Data Network's IMOS sub-facility, with data streams available as of the last update in May 2026. Observations are used for calibrating satellite data and feeding into operational weather and climate models.
Use Cases
- Calibrating and validating satellite-derived sea surface temperature data based on high-quality in situ observations.
- Improving operational regional and global sea surface temperature analyses for numerical weather prediction.
- Studying ocean temperature dynamics in data-sparse regions like the Southern Ocean and Bass Strait.
- Analyzing temporal and spatial coverage of sea surface temperature from a volunteer observing fleet.
Strengths
- Data is supplied in near real-time, within 24 hours, from participating vessels.
- Includes high-quality bulk SST data from sensors like Sea Bird SBE 48 and SBE 38, collected hourly from specific vessels.
- Covers diverse geographic routes including the Southern Ocean, coastal Australia, Bass Strait, Pacific Ocean, South-East Asia, and the Tasman Sea.
- Quality assured data is placed on the Global Telecommunications System and fed into operational validation systems.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Some historical data from four vessels is not available in real-time.
