GHRSST Level 4 OSPO Global Foundation Sea Surface Temperature Analysis (GDS version 2) for 2016-02-20 (NCEI Accession 0154487)

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) 基于最优插值 (optimal interpolation, OI) 算法在全球0.054度网格上以业务化模式每日生成。
极地融合海表面温度 (Sea Surface Temperature, SST) 分析产品将多颗卫星反演的海表面温度数据融合为统一的海表面温度分析结果。该产品整合了先进甚高分辨率辐射计 (Advanced Very High Resolution Radiometer, AVHRR)、可见红外成像辐射计套件 (Visible Infrared Imager Radiometer Suite, VIIRS)、地球静止业务环境卫星成像仪、日本先进气象成像仪 (Japanese Advanced Meteorological Imager, JAMI) 等传感器的日间与夜间观测数据，以及船舶、漂流浮标与锚定浮标的原位观测数据。本数据集专为用作数值天气预报 (Numerical Weather Prediction, NWP) 模式的下边界条件而研制，且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) 版本2的格式要求。
