Sea Surface Temperature Products


Approximate coverage of the Australian and Antarctic AVHRR receiving stations

The Sea Surface Temperature (SST) Satellite Remote Sensing Sub-Facility in a collaborative effort with the Australian Bureau of Meteorology produce high-resolution satellite sea surface temperature (SST) products over the Australian and Southern Ocean regions, designed to suit a range of operational and research applications.  All these products follow the latest International Group for High Resolution Sea Surface Temperature (GHRSST“GDS 2” file formats, assisting international data exchange and collaboration.

The highest spatial resolution (1.1 km x 1.1 km) data from Advanced Very High Resolution Radiometer (AVHRR) sensors on NOAA Polar-orbiting Operational Environmental Satellites (POES) can only be obtained through receiving direct broadcast High Resolution Picture Transmission (HRPT) data from the satellite.  In Australia, HRPT data is received by a number of agencies (Bureau of Meteorology, Geoscience Australia, AIMS and CSIRO) and consortia (WASTAC and TERSS) at reception stations located in Darwin, Townsville, Melbourne, Hobart, Perth and Alice Springs and in Antarctica at Casey and Davis Stations.

Instrumentation and Data

Mean AVHRR SST from Australian and Antarctic receiving stations for 1-28 February 2008, gridded at 0.02° x 0.02° resolution.

The Bureau of Meteorology, in collaboration with CSIRO Oceans and Atmosphere Flagship, combines raw data from these ground-stations and produces real-time, level 2 (geolocated, swath) and level 3 (gridded, composite) files containing either “skin” (~ 10 micron depth) or “foundation” (~ 10 m depth) SSTs.   The IMOS SST processing system aims to provide a consistent, accurate record of SST over an extended period of time from AVHRR sensors on all operational NOAA POES satellites from NOAA-11 to NOAA-19.  GHRSST format AVHRR SST products are available in near real-time over the Australian and Southern Ocean domains and have been reprocessed back to 1992.

For information on the IMOS receiving stations see the SRS Instrumentation page and for information on the SST processing and data products see the SRS-SST Data pages.
