OSTIA L4 SST Analysis for 2016-03-04 (NCEI Accession 0146064)

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.

本数据集为英国气象局以业务化运行模式每日生成的高分辨率海表温度工作组（Group for High Resolution Sea Surface Temperature，GHRSST）四级海表温度分析产品，该产品基于全球0.054度网格，采用最优插值（optimal interpolation，OI）方法计算生成。业务化海表温度与海冰分析系统（Operational Sea Surface Temperature and Sea Ice Analysis，OSTIA）所融合的数据源涵盖多类卫星传感器数据，包括甚高分辨率辐射计（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）以及热带降雨测量任务微波辐射计（Tropical Rainfall Measuring Mission Microwave Imager，TMI），同时纳入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具有高度平滑的特性，其研发目的是为数值天气预报（Numerical Weather Prediction，NWP）模型的海表温度数据同化工作提供支撑。
