GHRSST Level 4 OSPO Global Foundation Sea Surface Temperature Analysis (GDS version 2) for 2016-02-21 (NCEI Accession 0154474)

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 uses both daytime and 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.高分辨率海表温度工作组（Group for High Resolution Sea Surface Temperature，GHRSST）4级海表温度分析产品，由卫星与产品运营办公室（Office of Satellite and Product Operations，OSPO）采用最优插值（optimal interpolation，OI）算法，以业务化模式每日生成，网格分辨率为全球0.054度。 极地融合海表温度（Geo-Polar Blended Sea Surface Temperature，SST）分析产品将多颗卫星反演的海表温度数据整合为统一的海表温度分析数据集。该分析所用数据源涵盖甚高分辨率辐射计（Advanced Very High Resolution Radiometer，AVHRR）、可见红外成像辐射计套件（Visible Infrared Imager Radiometer Suite，VIIRS）、地球静止轨道环境业务卫星（Geostationary Operational Environmental Satellite，GOES）成像仪、日本先进气象成像仪（Japanese Advanced Meteorological Imager，JAMI）等传感器的昼夜观测数据，以及船舶、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）模式的下边界条件而开发。该数据集符合GHRSST数据处理规范（GHRSST Data Processing Specification，GDS）2.0版本的格式要求。
