GHRSST Level 4 OSTIA Global Foundation Sea Surface Temperature Analysis (GDS version 2) for 2017-05-31 (NCEI Accession 0163884)

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 Spinning Enhanced Visible and Infrared Imager (SEVIRI), the Geostationary Operational Environmental Satellite (GOES) imager, the Infrared Atmospheric Sounding Interferometer (IASI), the Tropical Rainfall Measuring Mission Microwave Imager (TMI) and in situ data from ships, drifting and moored buoys. This analysis was specifically produced to be used as a lower boundary condition in Numerical Weather Prediction (NWP) models. This dataset adheres to the GHRSST Data Processing Specification (GDS) version 2 format specifications.本数据集为英国气象局业务化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，采用最优插值（optimal interpolation, OI）方法，构建于全球0.054度网格之上。该业务化海表温度与海冰分析系统（Operational Sea Surface Temperature and Sea Ice Analysis, OSTIA）所采用的数据源涵盖：先进甚高分辨率辐射计（Advanced Very High Resolution Radiometer, AVHRR）、旋转增强型可见红外成像仪（Spinning Enhanced Visible and Infrared Imager, SEVIRI）、地球静止业务环境卫星（Geostationary Operational Environmental Satellite, GOES）成像仪、红外大气探测干涉仪（Infrared Atmospheric Sounding Interferometer, IASI）、热带降雨测量任务微波辐射计（Tropical Rainfall Measuring Mission Microwave Imager, TMI）的卫星数据，以及船舶、漂流浮标与锚泊浮标的原位观测数据。本分析产品专为用作数值天气预报（Numerical Weather Prediction, NWP）模型的下边界条件而研发。本数据集符合高分辨率海表温度工作组数据处理规范（GHRSST Data Processing Specification, GDS）版本2的格式要求。
