IMOS Air-Sea Flux Data from Research Vessels in Australian Waters

The IMOS Ships of Opportunity - Air-Sea Flux Sub-Facility collects quality-controlled meteorological and oceanographic observations from research and Antarctic resupply voyages in oceans adjacent to Australia. Data includes bulk air-sea fluxes and input observations for wind, temperature, humidity, pressure, precipitation, and radiation, processed using the COARE Bulk Flux algorithm. Observations are gathered from vessels like the RV Investigator and Aurora Australis, quality-controlled by the Bureau of Meteorology, and delivered on a near real-time basis.

Use Cases

• Validating and improving climate models based on high-quality air-sea flux measurements.
• Studying ocean-atmosphere heat and moisture exchange based on wind, temperature, and humidity observations.
• Analyzing regional climate variability in the Southern Ocean and waters around Australia based on voyage data.
• Calibrating satellite-derived oceanographic data based on in-situ shipboard meteorological measurements.

Strengths

• Data undergoes quality control at the Bureau of Meteorology and uses the COARE Bulk Flux algorithm.
• Observations are described as 'climate quality' and delivered on a near real-time basis.
• Instruments are part of a comprehensive annual calibration program.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to voyages in oceans adjacent to Australia.
