Description
Summary:Statement: The processing method is described in Beggs H., A. Zhong, G. Warren, O. Alves, G. Brassington and T. Pugh (2011) RAMSSA - An Operational, High-Resolution, Multi-Sensor Sea Surface Temperature Analysis over the Australian Region, Australian Meteorological and Oceanographic Journal, 61, 1-22 (http://www.bom.gov.au/jshess/papers.php?year=2011).

It is operated by a consortium of institutions as an unincorporated joint venture, with the University of Tasmania as Lead Agent.

This Regional Australian Multi-Sensor SST Analysis (RAMSSA) v1.0 system blends infra-red SST observations from the Advanced Very High Resolution Radiometer (AVHRR) on NOAA and METOP polar-orbiting satellites, microwave SST observations from the Advanced Microwave Scanning Radiometer-2 (AMSR-2) on GCOM-W, and in situ data from ships, and drifting and moored buoys from the Global Telecommunications System (GTS). All SST observations are filtered for those values suspected to be affected by diurnal warming by excluding cases which have experienced recent surface wind speeds of below 6 m/s during the day and less than 2 m/s during the night, thereby resulting in daily foundation SST estimates that are largely free of diurnal warming effects.
