Dataset: Regional Australian Multi-Sensor SST Analysis ( RAMSSA) (MCP)


Description

A real-time, high-resolution, Regional Australian Multi-Sensor Sea surface temperature Analysis (RAMSSA) system has been developed at the Australian Bureau of Meteorology as part of the BLUElink> Ocean Forecasting Australia project.
The pre-existing operational, 1/4° resolution, regional SST analysis system (Smith et al., 1999) has been modified to produce 1/12° resolution, daily SST analyses over the Australian region (20°N - 70°S, 60°E - 170°W).
The high resolution analysis system combines SST data from infrared (AVHRR and AATSR) and microwave (AMSR-E) sensors on polar-orbiting satellites with in situ measurements to produce daily “foundation” SST estimates (SSTfnd), largely free of nocturnal cooling and diurnal warming effects. The RAMSSA analyses are used in realtime as the boundary condition for the Bureau’s regional numerical weather prediction models (LAPS 0.375, MesoLAPS, TCLAPS, ACCESS-R, ACCESS-A and ACCESS-C) and to validate the BLUElink> operational ocean model (OceanMAPS) SST5m forecast/analyses.
