GHRSST Level 4 OSPO Global Foundation Sea Surface Temperature Analysis (GDS version 2) for 2017-05-26 (NCEI Accession 0163779)

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（GHRSST）四级海表温度分析产品，由卫星与产品业务办公室（OSPO）每日以业务化运行方式生成，采用最优插值（OI）方法，在全球0.054度网格上开展计算。
极地融合海表温度（SST）分析产品将多颗卫星反演得到的海表温度数据融合为统一的海表温度分析产品。该产品采用了先进甚高分辨率辐射计（AVHRR）、可见红外成像辐射计套件（VIIRS）、地球静止轨道业务环境卫星（GOES）成像仪、日本先进气象成像仪（JAMI）等传感器的昼夜观测数据，同时纳入船舶、漂流浮标与锚定浮标的原位实测数据。本产品专为用作数值天气预报（NWP）模式的下边界条件而开发，且符合GHRSST数据处理规范（GDS）2.0版格式要求。
