GHRSST Level 4 OSPO Global Nighttime Foundation Sea Surface Temperature Analysis (GDS version 2) for 2017-05-10 (NCEI Accession 0163589)

A Group for High Resolution Sea Surface Temperature (GHRSST) Level 4 sea surface temperature analysis produced daily on an operational basis at the Office of Satellite and Product Operations (OSPO) using optimal interpolation (OI) on a global 0.054 degree grid. The Geo-Polar Blended Sea Surface Temperature (SST) Analysis combines multi-satellite retrievals of sea surface temperature into a single analysis of SST. This analysis includes only nighttime data from sensors that include the Advanced Very High Resolution Radiometer (AVHRR), the Visible Infrared Imager Radiometer Suite (VIIRS), the Geostationary Operational Environmental Satellite (GOES) imager, the Japanese Advanced Meteorological Imager (JAMI) 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.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，由卫星与产品业务办公室（Office of Satellite and Product Operations, OSPO）依托最优插值（optimal interpolation, OI）方法，在全球0.054度网格上以业务化模式每日生成。该极轨融合海表面温度（Geo-Polar Blended Sea Surface Temperature, SST）分析将多颗卫星反演得到的海表面温度数据整合为一套统一的海表面温度分析产品。该分析仅纳入以下传感器获取的夜间观测数据：甚高分辨率辐射计（Advanced Very High Resolution Radiometer, AVHRR）、可见光红外成像辐射仪套件（Visible Infrared Imager Radiometer Suite, VIIRS）、地球静止业务环境卫星（Geostationary Operational Environmental Satellite, GOES）成像仪、日本先进气象成像仪（Japanese Advanced Meteorological Imager, JAMI），同时包含船舶、漂流浮标与锚泊浮标的现场观测数据。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开发。该数据集符合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。
