Enhancement of Measurements on Ships of Opportunity (SOOP)- Air Sea Flux (ASF) - multi-purpose research and resupply vessel Aurora Australis collects underway meteorological and oceanographic observations (including SST) during its voyages in Sub-Antarctic and Antarctic areas. Data products are quality controlled meteorological and SST observations, and bulk air-sea fluxes. <br /> <br /> The Aurora Australis is a highly sophisticated multi purpose vessel which is designed to fulfil the role of a research, supply expedition vessel capable of operating in tropical and polar regions. <br /> <br /> The Aurora Australis is a 95m, 3911t vessel and operates under the call sign VNAA. Cruise schedules are available at https://secure3.aad.gov.au/public/schedules/sitreps.cfm<br /> <br /> Real-time, Sea Surface Temperature (SST) is processed from the vessel's SBE 38 calibrated temperature sensor located in the water intake pipe at ~5 m depth.<br /> <br /> Research Vessel Real Time Air-Sea Fluxes, aims to provide with "climate quality" meteorological measurement systems, capable of providing high quality air-sea flux measurements and delivered to researchers on a near real-time basis. Observations are wind speed and direction, air temperature, relative humidity, air pressure, long-wave, short-wave, ultraviolet and photosynthetically active radiation and precipitation.<br /> <br /> Data streams are fed into the existing ship data management system, and broadcast via satellite back to Australia every 30 minutes. The observations are quality controlled at the Bureau of Meteorology and air-sea fluxes calculated using the COARE Bulk Flux algorithm. <br /> <br /> A daily file of 1-minute averages of the observations and a daily file of 5-minute average calculated bulk fluxes are generated shortly after 0000UTC and provided to eMII.
