GHRSST Level 4 OSTIA Global Foundation Sea Surface Temperature Analysis (GDS version 2) for 2017-05-18 (NCEI Accession 0164137)

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.本数据集为高分辨率海表面温度工作组（Group for High Resolution Sea Surface Temperature，GHRSST）四级海表面温度分析产品，由英国气象局依托全球0.054度网格，采用最优插值（optimal interpolation，OI）方法每日业务化生成。业务化海表面温度与海冰分析（Operational Sea Surface Temperature and Sea Ice Analysis，OSTIA）所使用的卫星数据来源包括先进甚高分辨率辐射计（Advanced Very High Resolution Radiometer，AVHRR）、旋转增强型可见与红外成像仪（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），同时整合了船舶、漂流浮标与锚定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。该数据集严格遵循高分辨率海表面温度工作组数据处理规范（GHRSST Data Processing Specification，GDS）2.0版本的格式要求。
