Your access to IMOS Research Vessels Real Time Air-Sea Fluxes data discovery and exploration is through the Australian Ocean Data Network (AODN) Portal.

The data streams collected aim to provide climate quality near real time meteorological measurements including wind speed and direction, air temperature, air humidity, air pressure, precipitation, solar radiation (down welling short-wave), infrared radiation (down welling long-wave), sea surface temperature (at 1m depth), and sea surface salinity.

The meteorological data streams are fed into the existing ship data management system, and broadcast via satellite back to Australia or New Zealand daily. The observations are quality controlled at the Bureau of Meteorology.  A daily file of 1-minute averages of the observations and a daily file of 5-minute average calculated bulk fluxes are generated. The data is contained in NetCDF format files and consists of input QC'd meteorological observations as well as calculated air-sea fluxes. The fluxes are calculated using the COARE Bulk Flux algorithm version 3.0. Calculated fluxes include, sensible heat, latent heat, outgoing long-wave, outgoing short-wave and heat due to precipitation. The calculated skin SST value is also provided.

Flags are provided to indicate which sensor (when multiple are available) has been used as input to compute the flux. QC flags are not provided as fluxes are only computed when good data is available.
