GHRSST Level 4 OSTIA Global Foundation Sea Surface Temperature Analysis (GDS versions 1 and 2)

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基于业务化运行流程每日生成的、符合高分辨率海表温度工作组（Group for High Resolution Sea Surface Temperature，GHRSST）四级标准的海表温度分析产品，采用最优插值（OI）方法，在全球0.054度网格上开展计算。该业务化海表温度与海冰分析（OSTIA）所使用的数据源涵盖多类传感器的卫星数据，包括甚高分辨率辐射计（AVHRR）、旋转增强型可见与红外成像仪（SEVIRI）、地球静止业务环境卫星（GOES）成像仪、红外大气探测干涉仪（IASI）、热带降雨测量任务微波辐射计（TMI），以及来自船舶、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（NWP）模式的下边界条件而研制。本数据集符合GHRSST数据处理规范（GHRSST Data Processing Specification，GDS）2.0版本的格式要求。
