OSTIA L4 SST Analysis for 2016-05-16 (NCEI Accession 0153626)

A Group for High Resolution Sea Surface Temperature (GHRSST) Level 4 sea surface temperature analysis produced daily on an operational basis at the UK Met Office using optimal interpolation (OI) on a global 0.054 degree grid. The Operational Sea Surface Temperature and Sea Ice Analysis (OSTIA) analysis uses satellite data from sensors that include the Advanced Very High Resolution Radiometer (AVHRR), the Advanced Along Track Scanning Radiometer (AATSR), the Spinning Enhanced Visible and Infrared Imager (SEVIRI), the Advanced Microwave Scanning Radiometer-EOS (AMSRE), the Tropical Rainfall Measuring Mission Microwave Imager (TMI), and in situ data from drifting and moored buoys. This analysis has a highly smoothed SST field and was specifically produced to support SST data assimilation into Numerical Weather Prediction (NWP) models.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，由英国气象局（UK Met Office）以业务化运行模式每日生成，采用最优插值（optimal interpolation，OI）方法，在全球0.054度网格上开展计算。业务化海表温度与海冰分析（OSTIA）产品所用数据源涵盖先进甚高分辨率辐射计（Advanced Very High Resolution Radiometer，AVHRR）、先进沿轨扫描辐射计（Advanced Along Track Scanning Radiometer，AATSR）、旋转增强型可见及红外成像仪（Spinning Enhanced Visible and Infrared Imager，SEVIRI）、先进微波扫描辐射计-地球观测系统（Advanced Microwave Scanning Radiometer-EOS，AMSRE）、热带降雨测量任务微波辐射计（Tropical Rainfall Measuring Mission Microwave Imager，TMI）等卫星传感器数据，以及漂流浮标与系泊浮标的原位观测数据。该分析产品生成的海表温度场高度平滑，专门用于支撑海表温度数据同化至数值天气预报（Numerical Weather Prediction，NWP）模型。
