BLUElink Regional Australian Multi-Sensor SST Analysis (RAMSSA), daily, 9 km resolution for 2016-02-24 (NCEI Accession 0146093)

A Group for High Resolution Sea Surface Temperature (GHRSST) Level 4 sea surface temperature analysis produced daily on an operational basis at the Australian Bureau of Meteorology using optimal interpolation (OI) on a regional 1/12 degree grid over the Australian region (20N - 70S, 60E - 170W). This BLUELink Regional Australian Multi-Sensor SST Analysis (RAMSSA) v1.0 system blends satellite SST observations from the Advanced Very High Resolution Radiometer (AVHRR), the Advanced Along Track Scanning Radiometer (AATSR), and, the Advanced Microwave Scanning Radiometer-EOS (AMSRE), and in situ data from ships, and drifting and moored buoy from the Global Telecommunications System (GTS). The processing results in daily foundation SST estimates that are largely free of nocturnal cooling and diurnal warming effects.

高精度海表温度工作组（Group for High Resolution Sea Surface Temperature，GHRSST）四级海表温度分析产品，由澳大利亚气象局基于业务化流程每日生成，采用最优插值（optimal interpolation，OI）方法，在覆盖澳大利亚区域（北纬20°至南纬70°、东经60°至西经170°）的1/12度区域网格上开展分析。该BLUELink澳大利亚区域多传感器海表温度分析（RAMSSA）v1.0系统，融合了甚高分辨率辐射计（Advanced Very High Resolution Radiometer，AVHRR）、先进沿迹扫描辐射计（Advanced Along Track Scanning Radiometer，AATSR）以及先进微波扫描辐射计-地球观测系统（Advanced Microwave Scanning Radiometer-EOS，AMSRE）获取的卫星海表温度观测数据，同时整合了全球电信系统（Global Telecommunications System，GTS）所提供的船舶、漂流浮标与锚定浮标的原位观测数据。经该处理流程可得到日均基础海表温度估算值，该结果基本不受夜间冷却与日增温效应的影响。
