Maritime Meteorological and Air-Sea Flux Observations from Australian Research Vessels

Offering quality-controlled meteorological observations and calculated air-sea fluxes from scientific and Antarctic resupply voyages in oceans adjacent to Australia. Data is collected from research vessels equipped with 'climate quality' measurement systems and processed using the COARE Bulk Flux algorithm. It includes variables essential for climate studies such as wind, temperature, humidity, pressure, precipitation, and radiation.

Use Cases

• Calculate bulk air-sea fluxes using the COARE Bulk Flux algorithm with input observations of wind, air and sea temperature, humidity, and pressure.
• Analyze spatial patterns of surface air temperature and humidity across the Southern Ocean, Pacific Ocean, and Indian Ocean from underway vessel tracks.
• Investigate relationships between shortwave radiation, longwave radiation, and precipitation rate to model ocean-atmosphere energy budgets.
• Study surface wind conditions and surface pressure systems encountered by research vessels during Antarctic resupply voyages.

Strengths

• Data undergoes quality control at the Bureau of Meteorology and is generated from 'climate quality' meteorological measurement systems.
• Includes a comprehensive set of variables essential for air-sea flux calculations: wind, air/sea temperature, humidity, pressure, precipitation, and radiation.
• Observations are collected from multiple major research and supply vessels, including the RV Investigator and Aurora Australis, covering significant ocean areas.

Limitations

• The specific temporal coverage, row count, and column structure are not provided in the input, limiting precise assessment of dataset scale.
• Data availability is tied to specific research and resupply voyages, which may result in spatial and temporal gaps in coverage.
• The dataset consists of multiple file formats (HTML, WMS, PNG, WFS) which may require specialized tools for unified analysis.

Provenance

Source

Australian Ocean Data Network, via the Integrated Marine Observing System (IMOS) Ships of Opportunity - Air-Sea Flux Sub-Facility.

Collection Method

Underway meteorological and oceanographic observations collected from instrumented research and supply vessels. Data streams are fed into ship data management systems, broadcast via satellite, quality-controlled, and fluxes calculated using the COARE Bulk Flux algorithm.

Freshness

Data is delivered on a near real-time basis, with daily files generated shortly after 0000UTC. The metadata was last updated in March 2026.

Geography

Oceans adjacent to Australia, including the Southern Ocean, Pacific Ocean, and Indian Ocean, with voyages extending to Antarctica, New Zealand, Fiji, Papua New Guinea, Timor Leste, and New Caledonia.
